Although that's rather easy to implement technically, it also creates
some kind of inconsistency.

Good, I'll rename it.

Hm? Doesn't parent..hash work? Or are you talking about something else?

This is starting to get complicated ... I'm not sure how far in this I
can go with this patchset, so for the time being I'll probably just
stick to refining the (plain) patchset feature.

Damn, I always forget about that.

The reason why I chose 16 is that (1) it's a rather commonly used
'small' number across gitweb and (2) it's a rather acceptable
'universal' upper limit for patchsets. There _are_ a few patchbombs
that considerably overtake that limit, but observe that this limit is
not an arbitrary limit on patchsets generated by the 'patchset' view,
but only a condition for which a link is generated from shortlog view.
We may want to have TWO limits here: one is the absolute maximum limit
to the number of patches dumped in a patchset (to prevent DoS attacks
by repeated requests of the whole history), and the other one is the
limit for autogenerated patchset links.
BTW, autogenerated patchset links probably make sense taking some
previous branch name as point of reference. e.g., if I have branch1
within the history of branch2, we probably want some (semi)automatic
way of getting a patchset for branch1..branch2 --of course, we also
want to do a shortlog between them, so that's a more general feature
we should think about.
