Git-svn has been giving me the following error for some time when calling "git svn dcommit":

RA layer request failed: PROPFIND request failed on '/svn/stf/branches/dev/sw%2Fdpemu%2Finclude%2FNetCnxn.h': 
PROPFIND of '/svn/stf/branches/dev/sw%2Fdpemu%2Finclude%2FNetCnxn.h': 
302 Found (https://oursvnrepo.net) at /usr/local/libexec/git-core/git-svn line 508

This only occurred when git detected a rename or copy.

Following the lead into git-svn.perl, 
and noticing that some of the '/'s in the path were hex-encoded 
and some were not, 
I changed the regex used to find chars 
to hex-encode in the relative part of the path 
to exclude '/'.  
It works, so far.  
I have included a patch.
