Details:

The following code now works in Matlab:


plot(1:10);
title('My title', 'my subtitle');


In Octave this throws an error, because the second string argument as subtitle
is not supported, yet.

Matlab introduced this additional feature lately in Version R2020b.

I have already received quite a few Matlab scripts that use this feature,
because it is a very convinient way to have a two line title. Yes, I know
there are other ways to achive this, but people seem to quickly accept this
new way of doing it, and I must say I do appreciate the easy way of doing it
as well.

In Matlab they also introduced a dedicated function "subtitle" to achive the
same thing. (I do not know about their underlying handles and graphics
objects...)

Do we want to make Octave also accept this second subtitle string in the title
function?
