well, the 'svn url' thing was just a patch, it never went in (at least
not the version i posted, and i can't recall any other version...)

this proposal seems to indicate that you'd have to set the SVNROOT env
variable first... if that's the case, then all we're gaining is a few
keystrokes, since you could just as easily do:
export SR=http://svn.collab.net/repos/svn
svn co $SR/trunk
svn cp $SR/trunk $R/tags/0.14.0
so what's the point? we've saved a few characters. in windows i
imagine it's also possible within their shell, right?
now by comparing it to the svn url stuff and so forth, you seem to be
indicating that the // would take on some kind of special meaning
inside a working copy... i'm failing to see how that could be
implemented usefully... does it mean "the url of the directory i'm
running this command in" or what? if so, that doesn't really seem very
useful to me, but maybe i'm missing something.
