You are right. I use this url to fetch svn repo

In fact, git svn clone again and git svn fetch will do nearly the same thing. So we could use these two commands either. I just get used to git svn clone.

  ***  i used this sed to fix it:
       sed -i "/refname = /a\\\t\t\$refname =~ s/~/%7E/g;" perl/Git/SVN.pm
       sed -i "/refname = /a\\\t\t\$refname =~ s/ /%20/g;" perl/Git/SVN.pm
       You can use the regex above to find the exact place (about line 93 )where the issue happens. I think after the sentence refname = ....,  variable refname should be right, but it seems not. Please examine if after that sentence, refname contains some symbol like ~ or " "(space). If it does, the command after that may not deal with it correctly. Please be kind to check it again.

unfortunately, after several days of work. The whole webkit is not converted into git repo, because I met another problem. It said index mismatch. And I was not able to solve it anymore. I plan to convert it later again. It's awful.

If you have any question, feel free to inform me. I always eager to help in my spare time.
