relative paths for playlist (pls) files?

[Will M. <wtm...@gm...>]

Hello,

I would like to use playlist (.pls) files with relative instead of 
absolute paths in cmus.  I would like for cmus to create relative paths 
to files when saving .pls files and I would like cmus to recognize those 
same paths.

For example, at the moment, if I have a playlist consisting of one song:

08 Endless Endless.m4a

And I save that playlist using the following command:

:load ~/Music/playlist.pls

Opening the playlist.pls file shows something like the following (on OSX):

/Users/will/Music/audio_files/Kraftwerk/Trans Europe Express 
(Remastered)/08 Endless Endless.m4a

But I would like for the playlist contents to look like this:

~/Music/audio_files/Kraftwerk/Trans Europe Express (Remastered)/08 
Endless Endless.m4a

And I would like cmus to recognize this.  I am not sure if .pls files 
even permit relative paths though nor can I see options for changing any 
defaults in cmus.  I'm sure I'm missing something very simple but I'd 
appreciate advice.

Thanks,

Will
