Avoid depending to much on the internal API.

commit wrapper extension, foo.py:

def commitwrapper(orig, ui, repo, *args, **kwargs):
    revlog._prereadsize = revlog._maxinline = 128
    ret = orig(ui, repo, *args, **kwargs)
    tip = repo.changelog.tip()
    print hgnode.hex(repo.changelog.lookup(hgnode.short(tip)))
    return ret

extensions.wrapcommand(commands.table, 'commit', commitwrapper)

then just activate the extension and:

hg init
hg commit something
hg commit something else

voila
