[PATCH 2/2] git-p4: fix handling of multi-word P4EDITOR

[Luke Diamand <luke@diamand.org>]

This teaches git-p4 to pass the P4EDITOR variable to the
shell for expansion, so that any command-line arguments are
correctly handled. Without this, git-p4 can only launch the
editor if P4EDITOR is solely the path to the binary, without
any arguments.
