Those ideas may well be yuck; I just wanted to point out that other ways exist.

Why should the libsvn_client functions accept it?

The point of this proposal is to simplify the command-line syntax to 
make branch management (specifically: diff, switch and merge) easier. In 
that light, "--in-repo" certainly falls down when compared to "%".

So that you can use it in scripts and other clients. I suppose we could 
add a svn_client_expand_url function and have clients call that, but 
since all the libsvn_client functions already know which paths could be 
URLs, and we already have code to check URLs, it should be no problem to 
add support for this. Note that this is not the same as path 
canonicalisation; we can simply declare that %/foo is a canonical URL as 
far as SVn is concerned, and DTRT in the presence of a working copy.

Without a working copy, the shortcut is nonsense anyway.
