[pacman-dev] makepkg proposal: passing arguments to VCS commands in new VCS pkgbuilds

Specific use case: an upstream subversion repo requires --username anonsvn --password anonsvn --non-interactive (SVN apparently doesn't allow passing these parameters in the URI), and I want to use the new format for VCS packages. If there isn't an obvious way to do this already, would it make sense to add a variable, say $vcs_opts, to the makepkg API, which would be passed to the checkout commands in the download_git(), download_svn(), ..., functions?
