replay broken if repository is not used at root

Hi folks

The svn_ra replay command is broken if not used at the repository root:

| ( 2 ( edit-pipeline ) 31:svn://svn.debian.org/svn/kernel )
| ( ANONYMOUS ( 0: ) )
| ( replay ( 8846 0 true ) )
on svn.debian.org works.

| ( 2 ( edit-pipeline ) 37:svn://svn.debian.org/svn/kernel/dists )
| ( ANONYMOUS ( 0: ) )
| ( replay ( 8846 0 true ) )
fails with:
| [...]
| ( open-dir ( 41:dists/etch/linux-modules-extra-2.6/debian 2:d3 3:d41 () ) )
| ( open-file ( 51:dists/etch/linux-modules-extra-2.6/debian/changelog 3:d41 3:c42 ( )) )
| ( apply-textdelta ( 3:c42 ( ) ) )
| ( abort-edit ( ) )
| ( failure ( ( 160013 90:File not found: revision 8845, path '/dists/etch/linux-modules-extra-2.6/debian/changelog' 64:/tmp/buildd/subversion-1.4.2dfsg1/subversion/libsvn_fs_fs/tree.c 315) ) )
(wrapped for better readability)
