Import of Mikael's guileint-1.5.2.tgz into Guile CVS ...
* defmenu.el, fcreate.el, guile-init.el, guile.el, guileint.el,
inda-scheme.el: Imported unchanged.
* cmuscheme.el.diff, comint.el.diff, scheme.el.diff,
xscheme.el.diff: Created by diffing Mikael's versions against the
nearest revisions I could find in Emacs CVS, so as to show the
changes made.
* README.mdj: Renamed from Mikael's `README'.
* README: New.
1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* guile.el (guile-frame-eval): Made interactive.
(guile-error-map): Added guile-frame-eval under "e".
1999-03-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guile.el (guile-file-readable-p, guile-find-file-noselect): New
functions. Sets buffer to scheme-buffer before doing there
action.
(guile-display-scheme-sexp): Use the above functions.
1999-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guile.el (guile-buffer-file-name): Version of buffer-file-name
which uses file-truename;

1999-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guileint.el: Add conditional in order not to load the interface
multiple times.
* guile.el (scheme-virtual-file-list-find): New function. Finds
an finfo entry using a file name. Uses `file-truename';
Replaced all assoc calls with scheme-vertual-file-list-find
everywhere.
(guile-real-safe-backward-sexp): New function. Can skip backwards
over special scheme hash-syntax.
(guile-send-input): Use `guile-real-safe-backward-sexp'.
1999-03-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* inda-scheme.el (scheme-electric-open-paren),
guile.el (guile-indent-or-complete): Use indent-for-tab-command
instead of scheme-indent-line.
* scheme.el: Merge changes from Emacs-20.3.
1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guile.el (guile-send-region): Bugfix: Calculate new value for
start if overlays have been skipped.

module before sending any other overlay belonging to that module.

1998-05-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guile.el: Added nil nil t arguments in calls to make-overlay in
order to make the overlays rear-sticky. (This is an adaption to
Emacs-20.)

* guile.el (guile-stack-frame-map): Need to be fset in Emacs-20.
Wed Oct 1 22:02:19 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* inda-scheme.el (inda-inferior-initializations): Disable
font-lock-mode in inferior-scheme buffers. (For some strange
reason, the inda-read-only-overlay modification hook gets called
when a character is inserted after the prompt if font-lock mode
has been activated.)

values.

`buffer-name' instead of `current-buffer' in order to obtain the
buffer name.

Mon Aug 25 16:21:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
