So people can make arbitrary prefixes for remote URLs with Git. For example, if you add the following to your ~/.gitconfig :
 [url "git://anongit.kde.org/"]
     insteadOf = kde:
 [url "git@git.kde.org:"]
     pushInsteadOf = kde:
Then you can git clone kde:amarok 

Currently post-review uses the prefix URL (kde:amarok) instead of the true URL (git://anongit.kde.org/amarok). This is a problem because people can make the prefix be whatever they want. This patch makes it use the true fetch URL.

Successfully resolved a prefix and also made this review (with no prefix).
