tdf#128009: Allow spaces in AutoText suggestions

Currently autotext entries with long names starting with spaces, or
containing spaces after first or second character, would never be
suggested when SvxAutoCorrCfg::IsAutoTextTip() gives true (set in
Tools -> AutoCorrect -> [x] Display remainder of name as suggestion
while typing), because only a single word no less than 3 chars long
left to cursor is considered a candidate for the name matching.

This change allows to consider multiple chunks of text left to the
cursor as the candidates for name matching. The chunks are 3-9
characters long, may start only between words, and have spaces,
including leading. Thus, AutoText entries with long names like
"  Dr Foo" will now be suggested for an entry like "lorem  dr f".
