[PATCH v2] contrib/hooks/post-receive-email: send individual mails to recipients

[Michael Adam <obnox@samba.org>]

This changes the behaviour of post-receive-email when a list of recipients
(separated by commas) is specified as hooks.mailinglist. With this modification,
an individual mail is sent out for each recipient entry in the list, instead
of sending a single mail with all the recipients in the "To: " field.

Signed-off-by: Michael Adam <obnox@samba.org>

Sorry, in the first version of the patch, I forgot to
adapt the generate_email_header() function fill the "To"
field only with "$recipient" instad of "$recipients".

Cheers - Michael
