This seems to be indented deeper then the other functions
(or gmail is whitespace damaging my view).
Please use one hard tab to indent here.

We prefer $(command) instead of `command`.
These should be adjusted.

Also, the "@@DIFF@@" string may not work here.
This is a template string that is replaced by the Makefile.

I don't think the tools in the mergetools/ directory go through
cmd_munge_script so this is not going to work as-is.

Can the same thing be accomplished using "git diff --no-index"
so that we do not need a dependency on an external "diff" command here?

I am not a regular p4merge user myself so I'll defer to others
on the cc: list for their thoughts.  It does seem like a good idea, though.
