1. suffixIs(string const &, string const &) returns the wrong result.
Attached a fix.

2. When the cursor is on the first row on the document, or in a row
that contains figinset, and the text is edited (adding/deleting chars),
the row isn't updated.
Also, when opening a document with a figinset at the top of the file, the
display is not updated once the eps file is rendered by gs.
This bug didn't exist on the version from 2000-09-15 (including the changes
in that day).
