statichttprepo: stop shadowing the `bytes` builtin
PyCharm flagged it, but I also misunderstood when looking at the code, because
the name implied a byte string, not a number.
from mercurial.i18n import _
from mercurial import changegroup, error, extensions
def abort(orig, *args, **kwargs):
raise error.Abort(_('this is an exercise'))
def uisetup(ui):
extensions.wrapfunction(changegroup, 'getbundler', abort)
