Have we decided that this is something we really want? It does sound very
annoying and restrictive.

With the speed of the new working coy code, shouldn't we wait to see how fast
that is before even introducing 'svn edit'?

Are there any other open-source version control systems that use the read-only
model? Isn't the reason 'p4 edit' is needed is to indicate to the server the
intentions to edit the file, which svn doesn't need?
