Cause: After the update to httpd 2.4.x, mod_dav started treating internal representation of URI as uri-encoded. However, mod_dav_fs did not uri-encode this internal URI reprensetation while mod_dav_svn did.
Consequence: This leads to double encoding when using mod_dav with mod_dav_svn. This breaks some versions of Subversion clients when using paths which need encoding and httpd 2.4.x.
Fix: Encoding part has moved from mod_dav to mod_dav_fs.
Result: Subversion clients now works when used with paths which need encoding.
