Why? While Emacs Lisp does indeed not have multi-line comments, there
are commands in Emacs for commenting and uncommenting regions.

Reloading the entire file is the real kludge here. Reading this
section in the manual should be helpful:

(info "(emacs)Lisp Eval")

I don't know of multiline comments, but I'm no emacs
expert, and no programmer either...
Anyway, perhaps you could use single-line commenting on a region;
lisp-interaction-mode and the comment-region command.
You have to mark the beginning of the region (C-spacebar)
to do so.

Thanks.  I should have found these on my own.

Thanks for both pointers. I will read them post haste
:)

Re: shuddering initial frame, dump-emacs, source

I got it working fine, thanks for your help. 

I think it is a little weird that you have to set the defaults in
two places.  

I also noticed the following: on the one hand, we have this:

M-: (equal (scroll-bar-mode . (())) (scroll-bar-mode nil))
t

But on the other hand, putting (scroll-bar-mode nil) into the
default-frame-alist causes the flickering appearance of a scroll
bar.  Is this a bug? How is Emacs detecting the fact that
(scroll-bar-mode nil) is not dotted?

In emacs lisp there's no multiline comment. You can use
comment-region / uncomment-region to comment several lines at once.

Otherwise you can use this trick: use a multi-line string as a
comment, like you do for documentation strings:

(defun my-fun ()
    " This
is the documentation
string of the function
my-fun that appears 
when you ask for the

I use the X11 version because I prefer the way it "feels" to the Aqua
versions, and also because it seems faster under X11 than it did under
Aqua.  However, it would be good for people to have the option to
"Macify" the X11 build if they want- I guess.  But I agree that the
default for X11 should be the default POSIX-type standard unless the
user chooses to change it.

Unfortunately, no it doesn't.  Whichever hook is run last, still
sets the colors for all other modes.

I tried a few variations on that too, and they all do
essentially the same.  I've used copy-face instead of setq to
change the font-lock- face.  I've used set-face-foreground to
change the color, and have tried it on the font-lock- face after
it has been changed, and on the fld-font-lock- face before it is
used to set the font-lock- face.

In all cases the results were the same.

Speedbar doesn't recognize double-clicks (Xemacs with Cygwin and Windows XP)

I am running XEmacs 21.4 with Cygwin under Windows XP.  I installed
Speedbar (the latest version), and despite the fact that it's supposed
to treat double-mouse-1 the same as mouse-2, it seems to ignore my
double-clicks.  This is highly inconvenient, since pressing both mouse
buttons at the same time to simulate mouse-2 is flaky, brings up the
unwanted context menu, etc.  Is this a known problem?  Is there a
fix?.. Please help!

Was that in XEmacs rather than Emacs?

I did the testing in XEmacs.  However, spot checks with GNU Emacs
showed the same results with a few more quirks thrown in for
good measure (some of the things that work in XEmacs cause font-lock
to be erratic in GNU Emacs).
