"svn log --limit" very slow with 1.8 client and 1.4 server

https://subversion.apache.org/reporting-issues.html directed me to
report issues to this mailing list.

With svn 1.8.x (tested 1.8.3 and 1.8.5), "svn log" is very slow against
older svnserve (tested 1.4.6) when specifying any path other than the
root of the repository.

eg.

$ time svn log -l1 svn://host/repo > /dev/null

real 0m0.039s
user 0m0.008s
sys 0m0.011s

$ time svn log -l1 svn://host/repo/trunk > /dev/null

real 5m55.153s
user 0m0.670s
sys 0m0.197s

This is a repository with about 35k revisions. From a glance at
wireshark, it appears as though the svn client is downloading the
complete log history before printing out any log messages.

Older svn clients do not have this issue (tested 1.6.17 and 1.7)

Thanks,
