Ugggh, yes, that's a dog's breakfast. This is what happens to that text
when I hit ^W ( mapped to gq} ) while formatoptions=rontcql :

Even though quoted, Vim still restores the malformatted numbered list,
unfazed by your sneaky look-alikes. So, what do you need to do to also
hold your mouth right? My guess is that:

'formatlistpat' 'flp' string (default: "^\s*\d\+[\]:.)}\t ]\s*")

isn't cutting it. In comparison, mine is:

let &flp = '^\s*\(\d\|\a\)\.\s*'

(That may be mentioned in the 2011 thread, IIRC. It's past midnight
here, so I'm taking shortcuts, before I fall asleep.)

I also initialise with:

set formatoptions=croqltn

But none of that is critical. (Can be ignored in your case, I think.)

Then use Bill's function:

function! NList_toggle()
if &fo =~ "2"
set fo-=2 fo+=n
else
set fo-=n fo+=2
endif
endfun

noremap <F2> :call NList_toggle()<CR>

(F2 suits here, because I have F1 turning line numbering off. I.e keep
them together.)

I can't think that anything else is needed. In your case, the "2" may
not be needed. See :h fo-table . But I often use an indented first line
in a paragraph, so that's pretty darn handy.

If you do get rid of the "2", then the conditionality would be:

if &fo =~ "n"
set fo-=n
else
set fo+=n
endif

P.S. Thank's Bill, for solving this in 2011.
