Fix shortenng of file names in MakeDisplayPath: it is not a good idea to slice an utf8 string at arbitrary offsets, we have to work on a docstring instead. We need unfortunately to switch back and orth between utf8 and docstring.
This is a candidate for branch too, although the bug is minor. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@40149 a592a061-630c-0410-9148-cb99ea01b6c8
