[PATCH 0/3] [RFC] Support for publishing projects at central site

This series implements a special variant of the 'add remote' dialog
designed for publishing new projects at a central site - it fixes
certain parameters and launches web browser during the push for
project registration in a repo.or.cz-like fashion. The feature is
aimed especially at corporate Git deployment.

This is not really meant for as-is application, of course, but more
to see if people think it is good idea to have this kind of functionality
in git-gui at all and how generic it should be. This mini-series depends
on pretty much all the other patches I have submitted tonight.
