SVN access over https (SSL)

[NightStrike]

Currently, gcc provides access to the svn repository using the svn
protocol (svn://) as well as the http protocol (http://).  Some
sourceforge projects (not saying gcc is on sourceforge.. just citing
examples) also allow secure access via https.  This has the nice side
effect of making svn work through annoying proxies.

Can gcc add support for https access as well as the current two methods?
