[fish] Fix fish key binding issues (#60)

Browse Source 
Although a major overhaul is ongoing (#67), it is not yet finished and
cannot be considered stable enough for the next release. This commit
fixes a few apparent issues with small change to the current
implementation.

- Fixed error when $TMPDIR is not defined
- Better escaping of file/directory names
- Splitted functions to workaround fish bug
