Hmm. I'm not sure about that--if the prop is set, and the user has
local mods, isn't it safe to assume that the user is doing it
intentionally?

Doh. Of course I skipped the obvious. Here's the update list of
behaviors (I've not included commit as that will call unlock):

svn:needs-lock behaviors:
=========================

Checkout:
- If svn:needs-lock is set on a file when the file is checked out, set
  the file to read-only.

Update:

- If svn:needs-lock is unset in wc, but update sets it: Set file to
  read-only.
- If svn:needs-lock is set in wc, but update unsets it: Set file to
  read-write.
- If svn:needs-lock is set or unset in both places: Do nothing.

Propset:
- Setting the svn:needs-lock property sets the file to read-only
  (It also canonicalizes the value to '*')

Propdel:
- Removing svn:needs-lock sets the file to read-write.

Propedit:
- If the property is changed via propedit, we need to canonicalize it
  to '*'.

Lock:
- If svn:needs-lock is set, the file is set to read-write.

Unlock:
- If svn:needs-lock is set, the file is set to read-only.
