Teach 'git hook list --porcelain <hookname>', which prints simply the
commands to be run in the order suggested by the config. This option is
intended for use by user scripts, wrappers, or out-of-process Git
commands which still want to execute hooks. For example, the following
snippet might be added to git-send-email.perl to introduce a
`pre-send-email` hook:
sub pre_send_email {
open(my $fh, 'git hook list --porcelain pre-send-email |');
chomp(my @hooks = <$fh>);
close($fh);
foreach $hook (@hooks) {
system $hook
}
