You can pass `--config extensions.color=` and `--config
extenions.pager=` as extra arguments to hg in order to enable these
particular extensions for a single invocation... but enabling them
just to disable their effects again seems rather silly. At any rate,
HGPLAIN=1 takes care of disabling both of these, unless I'm much
mistaken.

Still, I think it's important to spread the knowledge that hg
extensions can be temporarily enabled from the command-line. I feel
like Mercurial is much misunderstood.
