This patch is still highly experimental. There are some things I need to 
rework, and it's not really a solution you can use right now because it's 
against hg itself.

Setting HGRCPATH= is one option, but as Martin mentioned, you'll lose all user 
configuration: their username, ssh settings, diff options, merge settings, 
enabled extensions, etc.

Another option is to run all commands like this:

hg --config ui.debug=0 --config ui.quiet=0 --config ui.verbose=0 --config 
defaults.CMD= CMD

You'll also want to set LANG=C and possibly deal with other LC_* envvars. For 
stderr output, perhaps diverting it to a buffer and ignoring it would be best. 
That particular extension warning won't change the return code of any command, 
which I assume is getting checked.
