perf: fix perfrevlogrevisions --reverse
Currently, 'endrev' equals `len(revlog)`, a revision that does not exist.
When asking for the reverse order, the arguments passed to xrange are
`xrange(len(revlog), startrev)` which then crash.
We need to offset 'endrev' by one so we don't crash anymore. Also, we offset
'startrev' to ensure we get the same number of revisions with and without the
`--reverse` option.

Testing head checking code: Case D-6
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 6: single changeset, superseeded then pruned (on a new changeset unpushed) changeset
This is a partial push variation of case B-6
.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto another one,
.. * the new version is then pruned.

Actual testing
--------------
$ hg push --rev 'desc(C0)'
pushing to $TESTTMP/D6/server
searching for changes
abort: push creates new remote head 0f88766e02d6!
(merge or see 'hg help push' for details about pushing new heads)
