xdg-realpath (fix #66)
Intoduces the xdg_realpath
and unoption_path
helper functions.
Use xdg_realpath
in all places readlink -f was used (cloes #66 (closed))
All scripts are able to deal with the new behaviour of
xdg_realpath failing for nonexistant files
as checks for that already existed in all relevant places.
Adds the xdg-realpath
script to make the functionality usable outside of the xdg-utils (i.e. in combination with xdg-open)
