Relative `Path=` entries in .desktop files

[Sod.Almighty]

Hi everyone,

[Apparently formatted email is not acceptable on this mailing list. So 
here is a plain text version.]

What happens if the Path= line of a *.desktop file is set to a relative 
path? For example:

     Path=mydir

Or:

     Path=.

We at the AppImage project (https://github.com/probonopd/AppImageKit) 
are wanting to use relative paths in *.desktop files to refer to 
locations relative to the root of the application mount point. Please 
see the github issue at 
(https://github.com/probonopd/AppImageKit/pull/384#issuecomment-294278492) 
for details.

What do you guys think? Would this create some kind of conflict with 
existing path rules?

Cheers,
     Stuart.
