Support XSL attribute "column" and CSS 4 attribute "spread",
stored in loext:hyphenation-keep-type, to give better control
over hyphenation-keep. E.g. spread: both parts of a hyphenated
word shall lie within a single spread, i.e. when the next page
is not visible at the same time (e.g. the next page is not a
right page of a book).
– css::style::ParaHyphenationKeep is a boolean property now,
importing hyphenation-keep = "page" as true.
– type of ParaHyphenationKeep, including the new non-ODF types
is stored in the new ParagraphProperties::ParaHyphenationKeepType.
– default value of ParaHyphenationKeepType is COLUMN for
interoperability.
– Add checkboxes to Text Flow -> Hyphenation Across in
paragraph dialog:
* Column (previously: Hyphenate across column and page)
* Page
* Spread
– enabling/disabling them follows XSL/CSS 4/loext, i.e.
possible combinations:
* No Hyphenation across
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "column")
* Hyphenation across [x] Column
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "page")
* Hyphenation across [x] Column [x] Page
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "spread")
* Hyphenation across [x] Column [x] Page [x] Spread
(hyphenation-keep = "auto")
– Add ODF import/export
– Update DOCX import
– Add ODF unit tests
Note: recent implementation depends on widow settings: disabling widow
handling allows hyphenation across columns and pages not only in table
cells.
Note: RTF import-only, but not used bPageEnd has been renamed to bKeep.
Depending on the RTF test results, likely it will need to disable
the layout change, e.g. GetKeepType()=ParagraphHyphenationKeepType::AUTO,
if PageEnd uses obsolete hyphenation rule, i.e. shifting only the
hyphenated word to the next page, not the full line.
More information:
– COLUMN (standard XSL value, defined in
https://www.w3.org/TR/2001/REC-xsl-20011015/slice7.html#hyphenation-keep)
– SPREAD and ALWAYS (CSS 4 values of hyphenate-limit-last,
equivalent of hyphenation-keep, defined in
https://www.w3.org/TR/css-text-4/#hyphenate-line-limits).

Add new hyphenation option "Compound characters at line end",
equivalent of libhyphen's COMPOUNDLEFTHYPHENMIN, to limit bad
pattern based hyphenation of compound words using morphological
analysis of Hunspell.
* Add checkbox to Text Flow in paragraph formatting dialog window
* Store property in paragraph model:
css::style::ParagraphProperties::ParaHyphenationCompoundMinLeadingChars
* Add ODF import/export (loext:hyphenation-compound-remain-char-count)
* Add ODF unit tests
Note: slower Hunspell based hyphenation is used only if
ParaHyphenationCompoundMinLeadingChars >= 3 (we assume that
libhyphen hyphenation patterns cover the smaller distances
correctly). Hunpell based hyphenation doesn't introduce
new hyphenation breaks, only detects the stem boundaries
from the libhyphen based hyphenation breaks.
Follow-up to commit c899d3608d30f3ab4c2bc193c1fcd765221614a4
"tdf#158885 sw: don't hyphenate right after a stem boundary",
replacing hyphenation zone dependence with the new "Compound
characters at line end".
Note: preset COMPOUNDLEFTHYPHENMIN values aren't loaded yet
from hyphenation dictionaries.
Note: the suffix of the last stem of the compound is always
hyphenated, i.e. the distance limits only hyphenation
inside the stem, not inside its suffix or at the end of the
stem before the suffix.

Both parts of a hyphenated word shall lie within a single
page with ODF paragraph setting fo:hyphenation-keep="page".
The implementation follows the default page layout of
MSO 2016 and newer by shifting the bottom hyphenated line
to the next page (and to the next column, see last note).
Note: this is a MSO DOCX interoperability feature, used
also in DTP software, XSL and CSS.
* Add checkbox/combobox to Text Flow in paragraph dialog
* Store property in paragraph model (com::sun::star::style::ParagraphProperties::ParaHyphenationKeep)
* Add ODF import/export
* Add ODF unit tests
New constants of com::sun::star::text::ParagraphHyphenationKeepType,
containing ODF AUTO and PAGE (borrowed from XSL), and for the
planned extension ParaHyphenationKeepType of ParagraphProperties:
– COLUMN (standard XSL value, defined in
https://www.w3.org/TR/2001/REC-xsl-20011015/slice7.html#hyphenation-keep)
– SPREAD and ALWAYS (CSS 4 values of hyphenate-limit-last,
equivalent of hyphenation-keep, defined in
https://www.w3.org/TR/css-text-4/#hyphenate-line-limits).
Note: the implementation truncates only a single hyphenated
line, like MSO does: the pages can end in hyphenated
lines (i.e. in the case of consecutive hyphenated lines),
but less often, than before.
Clean-up hyphenation dialog by collecting "Don't hyphenate"
options at the end of the hyphenation settings, and negating them
(similar to MSO and DTP), adding also the new option
"Hyphenate across column and page":
[x] Hyphenate words in CAPS
[x] Hyphenate last word
[x] Hyphenate across column and page
Note: ODF fo:hyphenation-keep has got only "auto" and
"page" attributes, while XSL defines also "column".
Because of the interoperability with MSO and DTP,
fo:hyphenation-keep="page" is interpreted as
XSL "column", avoiding hyphenation at the end
of column, not only at the end of page.

Add hyphenation zone support, i.e. allow the specified
amount of extra space in lines instead of forcing hyphenation.
It's for limiting hyphenation, used especially with
not justified paragraph alignment.
Note: this is an OOXML interoperability feature,
used also in DTP software and CSS.
* Add checkbox to Text Flow in paragraph dialog
* Store property in paragraph model (com::sun::star::style::ParagraphProperties::ParaHyphenationZone)
* Add ODF import/export
* Add ODF unit test
* Add layout test
Note: extend SvxHyphenZoneItem::GetPresentation() with
missing No CAPS and No last word hyphenation options.
Note: fix OSL_ENSURE condition in SwTextFormatInfo::GetHyphValues().

Add paragraph property to disable automatic hyphenation of short
words based on a minimum character count.
Note: there is a (broken) global option for Minimum Word Length
at hyphenation, see "Minimal number of characters for hyphenation"
in Tools->Options->Language Settings->Writing Aids), but
for better/comfortable paragraph-level adjustment of typesetting,
add a paragraph property for it. The same option is available e.g.
in Adobe InDesign and in CSS Text Module Level 4 (hyphenate-limit-chars).
* Add checkbox to Text Flow in paragraph dialog
* Store property in paragraph model (com::sun::star::style::ParagraphProperties::ParaHyphenationMinWordLength)
* Add ODF import/export
* Add ODF unit test
* Add layout test
