FWIW, what I did in svncopy.pl was to break down the path then build it
up
level by level, trying to access each level, until I stopped getting an
error. This allowed me to work out the root for myself.

For example, given

http://subversion/svn/repos/trunk/proj1/core/src/wibble.c

I run through the following steps:

svn log -r HEAD http://subversion/ <== FAILS
svn log -r HEAD http://subversion/svn/ <== FAILS
svn log -r HEAD http://subversion/svn/repos/ <== Succeeds.

>From this I conclude the repository root is http://subversion/svn/repos/
