Should be really either "[PATCH 1/2]" or "[PATCH 5/4]" or "[PATCH 5/6]"
just in case for the next patch, because next patch _depends_ on this
one, and just in case of threading problem it should be marked as it;
it also makes easier to apply patches from emails saved as individual
files each.

Good catch, good thinking IMHO. Committer date has much better chance
to be monotonic than author date, and is more close related to 
_publishing_ date (author date is more of _creation_ date).

Lack signoff; if Junio forges it (or you reply that it should be
signed off), you can add from me

P.S. I wonder what other web interfaces do, for example cgit. I guess
that web interfaces for other SCMs like SVN::Web, ViewVC etc. do not
have this problem because they have only one, single date.
