Would you mind if I delayed that to a separate patch? It's a significant difference from the original update hook, so I think it's worth having that change separately documented.

Ah - no problem.  Done.

Devious.  Fixed as you suggest.

Show 9 quoted lines

Again; I think I'll fix that one as a separate patch as it is a change from the behaviour of hooks/update.

Done. I've taken the liberty of adding a pipe-to-cat, that I hope you'll forgive...

# Output to the terminal in command line mode - if someone wanted to
# resend an email; they could redirect the output to sendmail themselves
  generate_email $2 $3 $1 | cat

This is to force the deactivation of the pager for all the git commands that generate_email calls.
