Well, it is problem also from technical point of view. Currently we can
just stream (dump) git-format-patch output to browser (not forgetting
adding '--encoding=utf8' if it is not used already), and do not need
to have markers between commits. It is very simple code, which is its
own advantage.

extra header.
I don't know what can be done about X-Git-URL.

I just don't know if it would be best name. Perhaps 'patches' would
be better?

Errr... I meant here for the user, not for gitweb. To somehow denote
before patch itself the endpoints. Just like for diff _for_ a commit
we have commit message denoting :-).

What I meant here is that it would be IMHO enough to have 'patch' view
(or whatever it ends up named) be raw format / plain/text format only,
and leave HTML equivalent for extra options/extra format to 'log' view.

I see.

A pageful (100 commits) as hard limit against DoS attacks?
