Unfortunately this breaks "hg diff -r" -- not "hg diff" w/o
options.

My uneducated simplistic guess is that this happens because
external diff is called. But for the life of me I can't figure
out what exactly happens. So if someone had a pointer/idea why
the following fails it would be nice (for me) to share it.

...

def reposetup()
...
    cmd = commands.parse(ui, sys.argv[1:])[1:][0]
    # already when I use above line w/o the next
    # hg diff -r outputs nothing even though cmd is detected
    archivemode = (repr(cmd).split()[1] == 'archive')

thx

Way too complicated for me :-(
