vc-version-other-window seems to be losing small chunk(s) of files. To
reproduce it, retrieve the working version of gdb-ui.el or fortran.el with
this command (see a diff below). I think an earlier thread discussed a similar
problem with a different command. I've not noticed this problem before but I'm
baffled because it seems to also happen with an old Emacs (21.2).
