Munair, I applied your findings except the last one in r56662. The last one may be right although I don't know the code well.
Seems that github fork of the core SVN repository is not in sync.
Yes, the "alrieckert" GitHub fork stopped synchronizing when SVN URL got the secure "https:" connection.
I also had to clone again my local git-svn link repo then.
Does "alrieckert" know about the issue?
