[PATCH 0 of 1] revsets: max is there, but not min?

[Nicolas Dumazet]

Hello!

Any reason why min() is not included in revsets?
I was looking at how to find the first revision that
created a branch, and simply tried 'min(branch(stable))'
but that does not work ;)

Of course, limit(branch(stable), 1) works in this particular
case, but min() would be nicer!
