comment-dwim does not do what I mean

[Lars Magne Ingebrigtsen]

I don't have transient-mark-mode switched on.

If I set the mark somewhere, and I then hit `M-;', then the region is no
longer commented out like it used to be.

Is this meant to work this way, or is it just a bug?

M-; can't guess whether the mark you set was placed there because you
intend to get back there at some point, or because you intend to operate
on the region.
So you need to tell M-; which it is, and you do that by controlling the
"active"-ness of the region.  So C-SPC C-SPC ... M-; should do, as will
... C-u C-x C-x M-;

Yes...  but all other commands that work on the region ... work on the
region.  Now,  `M-;' no longer is `comment-region', but `comment-dwim',
which means that it's certainly legitimate to work the way it does, but
I'd rather prefer that it work the way it used to.  The way it is today,
the easiest way (by far) to actually do what I mean is to say `M-x
comment-region'.

Which is weird.

Wait a minute, hasn't M-; been comment-dwim for a _long_ time...?
Also I seem to recall that the no-region behavior of M-; is _ancient_
(even predating comment-dwim?), and not all that obscure, so probably
isn't the sort of thing to be messed with at least by default...

[BTW, one thing that annoys me about message-mode is that it rebinds
M-; to comment-region -- I often want to _remove_ a level of citation,
and expect M-; to work "normally" (like comment-dwim) ... but it
doesn't, it acts in oppositely from comment-dwim in that situation
:( ]

Message doesn't bind `M-;' any more (as of yesterday), so this should
now work.

You got it backwards: M-; has never been comment-region.
It's comment-dwim that brought the comment-region behavior to M-;

Oops.  Sorry.  I could have sworn that I remembered typing `M-;' before
to comment out code, but I must be misremembering, then.
