Hi Petr,

I wrote this limit-pipe script:

    http://sourceware.org/ml/libc-ports/2009-05/msg00056.html

but I never got around to making the hook use it.
I can do something like this to the post-receive-email script
we're currently using (with a probable PATH update):

-                generate_email $oldrev $newrev $refname | send_mail
+                generate_email $oldrev $newrev $refname |
+                  limit-pipe 524288 | send_mail

On second thought, that limit, 512KB (just made up by me, btw),
has to come from config, set via e.g.,

    git config hooks.email-max-size 524288

since it's per-repo policy, while the hook script is typically shared.

On the other hand, since no one has complained about overly-large
messages in 4 months, maybe it's not worth doing after all.

If no one says they want it (and provides a max message size),
I'll presume there's no need.  Same applies to libc-ports.
