run-help: Support for svn and git

[Jörg Sommer <joerg@xxxxxxxxxxxx>]

Hi,

calling run-help for svn or git is often not very helpful. svn has no
real information in the manpage and the infos for git blubb are in
git-blubb (not git). So, run-help should pay attention to the subcommand
for git and should call svn help subcommand |pager. My proposal:
