Why I can't use '.' as valid TO_LOCATION argument?

Because if only one location is given to bzr branch, it's the source
location, not the destination location.  It mean "branch from this
directory, creating a new one with the same final component".  For the
particular case of '.' perhaps there's no other interpretation but
"change this from a checkout to a branch", but if you say "bzr branch
../other" do I want to branch it to "./other" or do I want to make
"../other" branch from it's parent?

Perhaps the message could be better, at least.
