I think this is simply a bug: the only reason that function wants a
shell buffer is to access the name of the shell process running in
it.  It could instead fall back on some system-dependent default, and
perhaps also provide a way for Lisp callers to specify the shell.

Patches to that effect are welcome.  (I'm also in favor of moving this
function to subr.el, while at that.)
