tests: introduce 'seq.py' as a portable replacement for 'seq'...
tests: introduce 'seq.py' as a portable replacement for 'seq' OS X 10.6.8 doesn't have it, while 10.10 does. I'm not sure when it was added. It may be missing from other platforms as well. This currently doesn't handle the string manipulation options (-f, -s and -w in MinGW anyway), since there is currently no need for it. Since xrange defaults to starting at 0 instead of 1, and treats the end as exclusive instead of inclusive, the args need to be extracted instead of doing: xrange(*[int(a) for a in sys.argv[1:]]) Therefore, the step might as well be added, even though there is no current use.

Function to test discovery between two repos in both directions, using both the local shortcut
(which is currently not activated by default) and the full remotable protocol:
$ testdesc() { # revs_a, revs_b, dagdesc
> if [ -d foo ]; then rm -rf foo; fi
> hg init foo

> hg clone . a $1 --quiet
