In the above two hunks 'patch' view functions as "git show --pretty=email"
text/plain equivalent, but this duplicates a bit 'commitdiff_plain'
functionality.  Well, 'commitdiff_plain' has currently some errors,
but...

Here 'patch' view functions as "git format-patch", able to be downloaded
and fed to git-am.  Perhaps the action should also be named 'patches'
here?; it could lead to the same function.

By the way, there is subtle bug in above link. If shortlog view is less
than $patch_max commits long, but it is because the history for a given
branch (or starting from given commit) is so short, and not because
there is cutoff $hash_parent set, the 'patchset' view wouldn't display
plain text equivalent view, but only patch for top commit.

I assume that the link is only for 'shortlog' view, and not also for
'log' and 'history' views because 'shortlog' is the only log-like view
which support $hash_parent?
