I was going to say that I thought the situation outlined in the help to be
the "intended" behaviour, but I had a crash, and by the time my computer was
up again, there had been tjis exchange between you two, which made me
reconsider. Vince, I think your proposals have merit, the problem is
choosing between them. And however silly it may seem, I suppose that there
might some day arise a situation where having, even (let's go whole hog, and
in a 50-line VGA terminal) 47 zero-line windows, one single-line window, and
of course the command-line, would present some utility :-). Of course we can
set wh=1, but then if one or more windows are closed, or if less than the
maximum are opened to start with, there should IMO be a way to have the
current one take up the slack, so to speak.
At least, if the current ambiguous behaviour (which I personallt don't like,
but it's not for me to decide) is to be the norm, then it should be
documented, maybe even at several places, e.g. under 'wh', :all and -o.
For a "true soft" behaviour of &wh, the max no. of windows is of course the
integer quotient of (&lines - &ch - (&wmh < 1)) by (&wmh + 1).
