bug#7408: Linux patchutils: Development of the project?

[MON KEY]

Well, FWIW following is the toplevel/main interface to my elisp
implementation of Steel Bank Common Lisp's `map1' which in turn is
that implementation's high-level driver for its portable Common Lisp
mapping procedures.

Among other things, my port to elisp required adding a cath/throw
inside of a dolist b/c Elisp's `dolist' doesn't have `return'.

Indeed, I was as surprised by the same `dolist' disconnect which Jari
is currently poking at. What I found troubling was the process
required to locate the locus of this disconnect...  In so much as
Elisp code transitions silently between the two versions of dolist it
should do transparently.

BTW - the impetus for this routine was w/re incorporating more cl seq
fun into core but without the keyword overhead...
