This is where I semi-disagree. I'm fine with having a set of commands 
(tla cp, tla mv, tla...) which always work. And that will support people 
who want the "completely consistent" view.

But if I know what's going on, and don't like having to type 4 extra 
characters each time, or I want to use say Nautilus (or windows 
explorer). It would be nice if it would do what I want.

Also, tla mv,rm et al *won't* work in a darcs repository, or a bitkeeper 
repository, or a svn one.

So then you have to remember where you are again, and what command does 
what you want.

If they all used taglines (again a pipe dream, I know) then they all 
could use just plain mv, and they all wouldn't need to re-invent the 
wheel all the time.

And for the case where you can't have a tagline you have tla mv-id (and 
no tla mv) which will move a file id that has become dis-associated.

And then on commit or tree-lint you get a nicer error message:

   The file associated with id blah.c.id cannot be found.
   Did you move or delete the file [m/d]? m
   Supply the new filename: blahblah.c
   Renamed blah.c.id -> blahblah.c.id

   The file associated with id bliss.id cannot be found.
   Did you move or delete the file [m/d]? d
   Are you sure [y/N]? y
   Deleted bliss.id.
