re: use *repl-stack* instead of *repl-level*

[Tristan Colgate <tcolgate@gmail.com>]

Hi,

  Sorry, I'm not currently subscribed to guile-commits so couldn't
reply to the actual commit mail.

  The changes to use *repl-stack* mean that the default prompt now has
"scheme@(guile-user) [1]> "
rather than "scheme@(guile-user) [1]> "  (it's never zero as the stack
always has at least the top repl on it?
or something along those lines).

  Also, the removal of #:welcome means that my shell app now display
the Guile welcome message, which
is a bit irritating. I use start-repl for my snmp-shell app in
guile-snmp. It is true that it basically is guile with
with some modules loaded and some symbol resolution magic started up.
I've been thinking about it more
as an app in it's own right though (for the purposes of docs, and
presenting the user a less intimidating
experience).

  *version* and repl-welcome don't seem to be overridable (at least
not via a let). Could they be made into
fluids? or is the current "this is definitely guile", approach to be
enforced? Iknow I could just re-implement
start-repl and co, but that doesn't really seem in the spirit of things.
