Only because you're not used to it, I suspect.

Unfortunately it's a Windows shell meta-character (for environment variables
etc., a bit like "$" in Unix).

Maybe, though it never appears at the beginning in that syntax and always does
in this.

Huh? A few lines above, you said "how about" "++" after saying "+" didn't seem
obvious enough. But I agree a two-char prefix doesn't buy us much.

Of course, the syntax doesn't have to be a prefix string. It could, for
example, be parsed like an option, e.g. "--in-repo /trunk/foo", or implied by
the command, e.g. "svn repo-diff /trunk/foo /branches/foo".
