So, while "propedit" would be fit here, as we are editing a (branch) 
property/attribute, the name could be confusing for subversion users 
accustomed to the command editing file attributes.

Would something like "set" be better (bzr set option value)? other ideas?

I am also thinking about making the tree namespace the default, since 
.bzr/branch.conf travels with the branch when moving stuff around, while 
settings from locations.conf would have to be regenerated (or updated by 
hand). What would be the concerns? The wiki says that some options like 
post_commit are ignored due to security concerns (?), for instance.
