[Portland] xdg-utils: common return values [CORRECT PATCH]

[Jeremy White]

Hmm.  This has exposed some laziness on my part; I did not
do a full 'make scripts' prior to building my patch, I
was doing my testing only with xdg-menu.

But it leads me to question the value of having generated
files in CVS.  Why are we doing that?
