bug#19483: 25.0.50; out-of-date doc and Commentary in `font-lock' wrt `font-lock-syntactic-keywords'

[Drew Adams]

`C-h v font-lock-syntactic-keywords' says that the variable is obsolete
since 24.1.  But in font-lock.el, the code, multiple doc strings, and
the Commentary all rely on it.

Something is not up to date, it seems.  Whatever that is, it should have
been taken care of at the same time that this variable was declared
obsolete.  That's 4 releases ago, now.  As of Emacs 25.1, it will be 5
releases overdue.

That's right.

No, they just keep supporting it, because it's only "obsolete" and not
"removed".

Do you really want to advocate we remove features right away when we
decide they're obsolete?

The doc and Commentary should reflect the fact that it has been
declared "obsolete".  That's the point.

Strawman, again.  No one suggested that you remove any feature.

Read the bug report.  It's about the doc (including Commentary). 

When you deprecate something, the doc for it should state that it
is deprecated.  Everywhere.

That the doc was not brought up to date about this as soon as
the status changed to deprecated was a doc bug 4 releases ago.
The bug is still there.

Emacs is the self-documenting editor.  It should tell users
about itself accurately.

Oh, I missed that.  Then, yes, feel free to install a patch for that.
Most of the doc should simply be removed.

The bug status should not be "done"/"notabug", as long as the
problem exists.
