If a dump file has a Node-path: value with a leading slash, 'svnrdump load'
raises an assertion failure:
$ svnrdump load file://$PWD/rr < the-dump-filtered
lt-svnrdump: subversion/libsvn_subr/dirent_uri.c:1256: svn_relpath_dirname:
Assertion `relpath_is_canonical(relpath)' failed.
'svnadmin load' accepts paths with or without a leading slash. All dump file
readers should behave the same way.
The dump file documentation in <notes/dump-load-format.txt> is not explicit. The
examples show no leading slash. The documentation should be made explicit.
