sw comments on frames: improve doc coordinates -> doc model pos conversion

In case an as-char image at the end of a paragraph was commented and the
user clicked past the end of the paragraph, we defaulted to extending
that comment, rather appending content. (The cursor was placed between
the as-char image and the comment anchor, not past the comment anchor.)

This doesn't seem to be useful, probably the expectation is that if the
user clicks before the comment anchor then we extend the comment range,
and if the click is after the comment anchor, then we don't. In both
cases we used to *select* the comment anchor, so typing a character
deleted the comment instead.

This commit is a step in the direction of never selecting the comment
anchor: now if you click past the comment anchor, then we place the
cursor after the comment anchor.

(But clicking before the comment anchor results in unchanged behavior
for now.)
