dispatch: show empty filename in OSError aborts

Mercurial would sometimes exit with:
  abort: No such file or directory
where str of the actual OSError exception was the more helpful:
  [Errno 2] No such file or directory: ''

The exception will now always show the filename and quote it:
  abort: No such file or directory: ''

Minimal hgk check
