Well...  That does work, and it's better than my version (I just added
a "| grep -v '/$'" to the `svn ls' part), but I'd say that a script
that uses two stdin redirections, and a two levels of nested subshells
is only short in its physical size...  (BTW, I don't think that there
is a way to make the sed expression better -- you want the first .* to
be non-greedy, but IIRC sed is pretty limited...)

Now the real exercise would be to make that into something that can be
put on a FAQ, with instructions that are sufficient for random people
to copy, use, and modify for other situations and other properties.
This is, IMO, the impossible part.

So I still think that there is a point in adding a command line flag.
For my own usage such hacks are enough so I'll shut up now.
