Some further analysis of the problem:

But actually, the "bad thing" IMHO is the naming clash introduced by the
symlinks that v(irtual)env is setting:
Why does it ignore the otherwise clear distinction between python and
python3 ?
When Vinay ported virtualenv to Python 3, we made the decision that
since virtualenvs generally have exactly one Python interpreter of one
version, that it would be less surprising if every virtualenv always had
a "python", regardless of 2v3. I don't know for sure if that was the
right choice or not.
Well, I'm struggling quite a bit with that and would love to at least have
the option to keep things uniquely named, the same way as the
system pythons are.
Actually, I would love to have both python2 and python3 in the same
virtualenv, for testing purposes, distinguishing the versions by using
the different interpreter, only.
But installing both versions after another messes things up very much
and led to the effect that I always got python3, even if I explicitly ran
(virtenv) $ python2
Python 3.3.0 (default, Dec 29 2012, 18:23:00)
...
And who is responsible to make things "right":
Should virtualenv avoid this naming problem,
or should the mercurial installer become more carefully specify its
interpreter?
In general, I think that it is wrong for system-installed scripts to
ever use "/usr/bin/env python" in the shebang line, as that makes it too
easy for them to be run with the wrong Python. I know that, for
instance, it is the policy of Debian/Ubuntu to not use "#!/usr/bin/env
python". I don't know what homebrew's policy is, but I'd suggest raising
this as a bug in the Homebrew Mercurial package.
Thank you. Yes I feared that I would have to prove it to be a hg bug
(again), not always the nicest experience ;-)
thanks a lot for your answer
