>From what I know of git-mergetool, you can use one of the predefined
merge tools: kdiff3, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff,
ecmerge, and opendiff (optionally providing path to the tool)

To add support for P4Merge you would have either modify
git-mergetool.sh (and, optionally, send a patch to git mailing list),
or make use of `mergetool.<tool>.cmd` configuration option.
Unfortunately there is no example...
