rHG81d35d5d35f9: bookmarks: introduce a repo._bookmarks.changectx(mark) method and use it
Summary

Many places were doing repo[mark], which usually works, but it's
slightly incorrect: if the bookmark has a name that matches a full hex
nodeid of another node, then the context for the other node will be
returned instead. Also, I'm about to remove support for
repo[<namespace thing>] :)

How do you feel about changectx instead of ctx? This would seemingly jive with other naming throughout the code base.

I agree, that's better to make it clear that it's not some kind of bookmark context. Will change.
