Details:

As noted in bug #44978, horzcat and vertcat both allow empty argument lists
and return an empty matrix. Shouldn't strcat do the same?

This change will technically make strcat Matlab incompatible (in that it
doesn't throw an error) but I think we've agreed that it's ok in general for
Octave to do something different when it's fed something that would be an
error in Matlab.

This should be an easy fix, but let's see if there are any strong opinions
about whether this should be done or not.
