Shouldn't be too difficult ... execpt ...

... except I have no idea how to add an option to an existing
command (which would be indeed the best way to do it) without
messing with hg code. Is this possible from the extension as well
(basically only the option has to be allowed, I can query the
command from the extension)? If yes, could you give some kind of
pseudo code?

That's why creating a new command, like "kwarchive", wouldn't be
the way. OTOH the extension already /does/ expand if it is
enabled.

Hm. Perhaps this could be done via config, like if I had
something like

[keyword]
archive = expand

this would trigger expansion when archive is called.
