The terminology is a bit confusing. Does 'locked' mean that the file is
read-only and you have to get an access key from the repository, or does
it mean that you have acquired a lock on the file so that only you can
change it?

That is certainly true :-(

It would be useful to indicate that you are holding a key/lock, and you
should release it if you are not using it. This use would take
precedence over the in-subversion overlay, so after you commit changes,
your locked files show up as needing to be released.

It would also be useful to have an icon indicating that you do not have
a key/lock, and you need to acquire one in order to access this file.
This is almost identical to the above case, but with the opposite sense.

But that is 2 extra overlays which we can't afford.
