bug#5106: 23.1.50; global-visual-line-mode breaks find-file minibuffer usage

[Matthew Dempsky]

Normally pressing C-a while using find-file will place the point
immediately after the "Find file: " prompt, but after turning on
global-visual-line-mode, C-a will place the point at the start of the
minibuffer; i.e., before the "Find file: " prompt.

I guess beginning-of-visual-line should constrain to field boundaries,
like move-beginning-of-line.  I've checked in a fix.  Thanks.

I can confirm C-a is fixed, but I just noticed C-b still moves past
field boundaries too.

Actually, this happens regardless of whether visual-line-mode is in
use, though I believe C-b used to stop at the prompt.  Maybe this was
an intentional change?  (If so, I wouldn't say I'm opposed; just
making sure it's not an inadvertent regression.)

C-b and C-f have always ignored field boundaries, AFAIK.

Are they just disobeying, or?

No, it's just that without it, it can become too difficult to escape
the field.

Ah, that's possible.  I mistakenly assumed Aquamacs's behavior
regarding this was the default in GNU Emacs too, but I see now that
part of aquamacs.el is:

  (setq minibuffer-prompt-properties
	(plist-put minibuffer-prompt-properties
		   'point-entered 'minibuffer-avoid-prompt))

Sorry for the bad assumption.
