Message-ID: <7dvauuyruh.fsf@fencepost.gnu.org> (raw)
In-Reply-To: <83si0b8q7t.fsf@gnu.org> (Eli Zaretskii's message of "Mon, 29 Feb 2016 17:56:54 +0200")


So this seems like a mess.

fill-column is documented to be an integer, and that is its custom-type.
Nowhere does it say it can be nil, AFAICS.
Many places in Emacs are not prepared for it (or current-fill-column) to
be nil.

Yet 1e87252 explicitly added a check for a nil fill-column to
current-fill-column. AFAICS, do-auto-fill is the only place in Emacs
that tests for this, and uses it to disable auto-fill.

The only uses I find for "(setq fill-column nil)" are a few people using
it in their .emacs to disable auto-fill (I guess) in some major mode.
The idiomatic way to do this is just to turn off auto-fill in that mode.

TLDR:
Let's remove the test for nil fill-column in current-fill-column.
