From: Ben Keene <seraphire@xxxxxxxxx>
Add an additional hook to the git-p4 command to allow a hook to modify
the text of the changelist prior to displaying the p4editor command.
This hook will be called prior to checking for the flag
"--prepare-p4-only".
The hook is optional, if it does not exist, it will be skipped.
The hook takes a single parameter, the filename of the temporary file
that contains the P4 submit text.
The hook should return a zero exit code on success or a non-zero exit
code on failure. If the hook returns a non-zero exit code, git-p4
will revert the P4 edits by calling p4_revert(f) on each file that was
flagged as edited and then it will return False so the calling method
may continue as it does in existing failure cases.

git-p4: Add hook p4-pre-pedit-changelist
Our company's workflow requires that our P4 check-in messages have a
specific format. A helpful feature in the GIT-P4 program would be a hook
that occurs after the P4 change list is created but before it is
displayed in the editor that would allow an external program to possibly
edit the changelist text.
My suggestion for the hook name is p4-pre-edit-changelist.
It would take a single parameter, the full path of the temporary file.
If the hook returns a non-zero exit code, it would cancel the current P4
submit.
The hook should be optional.
