bug#21695: 25.0.50; Change most occurrences of `setq' in Emacs manual to `customize-set-variable'? Really?

No, I'm saying that (for most variables) Emacs doesn't know that there's
a :set on the variable when loading .emacs.  And that's fine.

Also for variables where Emacs knows there a :set (which would then
issue the warning), it's also fine, because loading the .el file works
perfectly.  Most of the :set thingies are for when you've already
started the mode/package and then change things "in flight".

No, displaying a useless warning (and it will be useless in the vast
majority of the cases) isn't good.

I haven't really been paying attention to this bug report after closing
it -- we're not going to change the manual as requested, and it's fine
to use setq in .emacs.  If we're to do something about this, then
somebody would have to go through all the defcustoms with :set and try
to identify some that should, indeed, not be set with setq and tag them
up.  (There aren't a lot of these.)

Which is why I closed this bug report in the first place.
