[Octave-bug-tracker] [bug #49444] tilde output argument requires comma for parsing

[Francesco Potortì]

Follow-up Comment #9, bug #49444 (project octave):

Note that in the above expressions, the comma can be omitted in the list of
output args, so for example

     [a, b] = [u, s, v] = svd (a)

is equivalent to

     [a b] = [u, s, v] = svd (a)

However, when using a tilde (~) as a placeholder for an output arg, you cannot
omit commas between args.  The reason is that the tilde is also a negation
operator and the comma is needed to distinguish the two uages.
