Two questions.

 (1) There has long been a support for specifying where your
     out-of-PATH receive-pack and upload-pack are to be found.
     Is it inadequate, and if so why?

 (2) data->receivepack is copied to args.receivepack in
     git_transport_push() and then eventually given as prog
     parameter to git_connect(), which is sent to the shell on
     the other end.  If the git restricted shell is in use, that
     is compared to the list of commands shell.c::cmd_list[];
     and separating "git-receive-pack" into two words like your
     patch would break it, I suspect.  Have you tested this
     codepath?

In the longer term (definitely before 1.6.0), we should rethink
the way --receive-pack (given to "git push") and --upload-pack
(given to "git fetch") options are handled.  We are heading
towards "a single git binary to rule them all", so it might make
sense to deprecate these two options and instead have the caller
specify the path to "git" itself (which in turn knows how to
invoke receive-pack and upload-pack subcommands).
