[PATCH 2/3] git-gui: Use git web--browse --stdin for safe URL passing

The current code does not actually require this since the documentation
URL should always pass through unmangled, but future users of
start_browser() (as in the patch to follow) might require this.

This patch has been sponsored by Novartis.
