bug#7253: comment-dwim should easily allow mid-line comments

[jidanni]

Sometimes I want to make a comment in the middle of a line, not at the
end, but whenever I hit M-;, prefix or not, comment-dwim insists on
putting it at the end of line, at least in html-helper mode.
emacs-version "24.0.50.1".

How would you tell Emacs that your intention is to make it in
the middle?

Excellent question. One would think adding a prefix argument to M-;
would be good... but that probably already is taken... and wait, M-; is
bound to different commands in different modes... Yuck. E.g., as I write
this it is bound to comment-region.

Hi,

as per chance played with commenting a little bit:
do you may present a show-case, where such a feature makes sense?

See a lot of difficulties beside: does "in the middle" mean splitting 
words if existing there?

No, M-; should usually not be rebound in major-mods.

Sounds like a misfeature of the major mode you're using.  Can you give
us some details?

I've now removed the binding from message-mode.

Thanks.  It might make sense for message-mode to redefine the binding
somewhat since it's not really a programming mode, but this binding
means that M-; can't be used to un-quote, so it's not a good idea as
it stands.

major-mode ^U^X^E message-mode

M-; (translated from <escape> ;) runs the command comment-region,
which is an interactive autoloaded Lisp function in `newcomment.el'.
