* Paragraph.cpp (isChar): new method; returns true when pointer is on a character that is not a letter. Note that a footnote inset, for example is neither a letter nor a character. * Text.cpp (cursorForwardOneWord, cursorBackwardOneWord): rewrite by using 3 character categories: letters, characters and others. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@25373 a592a061-630c-0410-9148-cb99ea01b6c8
