svn:externals: same relative path to different repository

As a previous CVS outfit, we've used the cvs2svn to bring all our
modules to SVN. We did this 4 or so years ago, and we've been chuging
along with SVN ever since.

But using the old metaphore of different CVS modules to achieve a
similar product, we've had to parallel-branch, using svn:externals
definitions. We find this work to be more than it's worth, and when 1.5
came out with relative paths in svn-externals definitions, we were
excited about what was coming.

The release fell far short. I was hoping to define an svn:externals to
say, "use the same relative path to this URL in a different repository."
For example, if my "foo" trunk had an externals defined to the "bar"
repository, I'd like to branch both "foo" and "bar", and when I check
out "foo" I want the "bar" reference to use the relative path that was
assigned to "foo."

I hear echos of this same desire at the bottom of bug 1336.

Here's my suggestion, in the form of shell text. I just used a "$"
symbol below to define that "same relative path..." This "$" is to
compare with the ^ used for the beginning of a URL definition.
