[PATCH] hooks/post-receive-email: do not truncate messages at a '.' line

When sendmail is reading an incoming message, by default it will terminate it if it reads a dot on a line by itself.

The post-receive-email script can generate such a line if the message in a tag object contains a dot ('.') on a line by itself.

There are two options to turn off this behavior, -i and -oi which are equivalent.

The choice of which to use is based on the observation that -i appears to be the more commonly used option for this and that all current sendmail-compatible programs appear to accept both.

Therefore add the -i option to the invocations of /usr/sbin/sendmail to avoid prematurely terminating the input message at the occurence of a dot ('.') on a line by itself.

BTW, what is the status of post-receive-email?

I find it quite useful for a minimal server that only needs Git binaries and a POSIX shell.

The only real issue with it I'm aware of is that if multiple branch heads are updated in a single push and two or more contain the same new revison(s), those revision(s) will be incorrectly omitted from the emails sent out.

I have a patch to correct that, but it's not quite as simple as this patch and would need more review, so I don't really want to send it out and waste folks' time if there's no interest in picking up updates to contrib/hooks/post-receive-email.
