bug#23151: 25.1.50; Emacs should have a convenient command for saving unchanged buffers

Uh, 3 people?  OK, 3 out of the 3 who bothered to say something about
this.  But "virtually everybody" might be a bit of an exaggeration, no?

No, it does not mean that.

(But I have no objection to your adding such a command.)

I would object, for one.  If you feel you must add a command, add
a command.  But please do not mess with `C-x C-s'.

Yes, of course they do.  Hard to believe you wonder about this,
or would even consider changing the UI of `C-x C-s'.

Just add the command.  Users can bind it themselves, if they like.
Time will then tell whether Emacs should at some point bind a key
for the command by default.

5) Use `C-u C-x C-w RET' instead of `C-x C-s'.  If you like, bind
that to another key.

Much ado about nothing, IMO.
