Uh, yah. svn:lock was a crappy name if it doesn't indicate if a lock
is held, but that the file should have mandatory locking enabled.
(This answers my question to ghudson from a few minutes ago.)

And as ghudson said, we might be better off to split the implementation
of directory locks until after we have file locking in place.

Agreed that you wouldn't want to store other people's lock tokens.
However, svn st -u (or whatever) would indicate whether a lock is held
at that moment, right? So, there is a way to see if a lock is held on
the server side?

Honestly, they'd use GUIs. The GUI can say, "Do you want me to update?"
right after the lock is taken.
And, remember that most non-techies are going to be using Adobe Photoshop,
Mac OS X Finder, etc, etc. They all hide the lock/unlock business from
*ahem* We are planning for the locking API to be able to be DAV-compliant,
right? =) The real non-techies aren't going to know there's Subversion.
They are just going to open it up with Photoshop...

Yup. I'd go with '.mine' to be consistent. And, then 'svn resolved'
could clean it up??

So, say you. =)

Not required, but they should be present. I'd view it as similar to our
'svn commit' messages. -- justin
