My quick thoughts on this problem: The simple (relatively speaking) solution
seems to be a hook in svn copy that will look at the svn:externals property on
the directory being copied, check the revision # of each external lib, then fix
up the svn:externals property to include the revision number before committing.

Of course, there could be a switch to turn this automatic update on/off, in case
you wanted your copy to continue tracking the trunk of the external lib(s).

This isn't exactly the same as CVS - as Ben Collins-Sussman brought up on IRC,
it doesn't quite work out for branches. CVS users would expect external libs to
automatically branch when they create a main project branch.

If you are using your copy as a tag, however, it works out fine. Personally,
since I have very little prior experience with CVS, I wouldn't expect automatic
branching of external libs anyway.

Thoughts? Would libsvn_client/copy.c be the place to implement this?
