because swank:operate-on-system-for-emacs calls asdf:operate-on-system
directly without going through a backend function (unlike compile-file
and compile-string) and therefore the openmcl backend doesn't have the
opportunity to bind *buffer-name* and *buffer-offset*, which are
specific to the openmcl backend.

we could either make operate-on-system-for-emacs go through a backend
function, or make swank-compiler (which all three functions use) a
backend function/macro which implementations could use to bind
whatever state variables they need.
