default buffer-enable-undo

default buffer-enable-undo

[David L]

I installed emacs from CVS yesterday and I noticed
today that buffers are sometimes opened without
buffer-enable-undo turned on.  The way I discovered
this was when I got the splash screen message that
says press C-l to begin editing and I pressed C-I
instead of C-l (capital eye instead of lower case el)
and my buffer had a tab inserted at the beginning.
I tried to undo this and it said that the buffer didn't
have any undo information.  That behavior is
different from 21.4.1.  Is this a bug or some
intentional new feature that I have to work around?
I haven't figured out when undo is available and
when it isn't, but I suspect it has something to do
with binary files... both times I've had no undo
by default, I was editing binary files.

Thanks...

PS - Other than these quirks, I'm impressed with
what's in CVS right now... the new gud interface
is particularly nice (at least judging from the few
minutes I've tinkered with it).  Thanks developers!

Do you see the same behaviour when you invoke GNU Emacs from CVS with  
-Q? If yes, then it looks like a bug, if no, then you need to change  
your init files.
