Amusing. I didn't see Scott's patch.

But, in my testing, for things to work properly I needed to use
launchp4merge per:

http://kb.perforce.com/AllPerforceApplications/StandAloneClients/P4merge/CommandLineP..rgeOnMacOsX

And I also found things didn't work properly unless I provided an absolute path.

(Aside, the "right" way to launch p4merge, at least on 10.6 would be:

/usr/bin/open -b com.perforce.p4merge -W -n --args <args to p4merge...>

This way OS X's launch services would find p4merge.app wherever it is
on the user's system. But, I think some of these options to open are
10.6 specific and in practice looking in /Applications and
$HOME/Applications I think is a sane enough default.)
