pytype: work around wrong ImportError flagging
As documented in https://github.com/google/pytype/issues/163, newer versions
of Pytype do not understand caught `ImportError`, so we temporarily ignore
them where applicable.
# extension to emulate interrupting filemerge._filemerge
from mercurial import (
error,
extensions,
filemerge,

def failfilemerge(*args, **kwargs):
raise error.Abort(b"^C")
def extsetup(ui):
extensions.wrapfunction(filemerge, 'filemerge', failfilemerge)
