Yes, sorry for being not clear.  I meant both specifying
SmDiscardCommand and deleting file manually when user closes Geany.

No, we need to look for absolute path if and only if Geany is run using
relative path.  When Geany is run either using absolute path or without
any path at all, we can leave the path as is.  GNOME's session manager
does not work only with relative paths.  Getting absolute path from
relative to current directory is ~5 lines without any hacks.
