I think it makes more sense to add a generic option to Bazaar that can
be easily used and make use of that in more places than to add a global
option. 

E.g. allowing "directory" in the takes_options array like we already
allow "revision". What commands are there that you think could use -d
but don't support it at the moment?

There is not actually a need for every command to support this option.
E.g. "bzr log", "bzr branch", "bzr checkout" and "bzr diff" take a path
already.

I also don't think it is actually necessary to change the directory in a
lot of situations and that it can actually be harmful since *all* paths
would be interpreted relative to the option specified in --cd. For
example, take "bzr push -d ../somedir subdir". This would behave
differently when used with an option that does an actual chdir.

That said, I very much like the -d option, and agree it should be
available in more places.

Cheers,

Jelmer
