Yet another corner case involving concatenation.

In Octave, this code produces an error

However, in Matlab it succeeds with a result of [1], but it does throw a warning message.

The related code where the concatenated matrix is 0x0 works, and produces no error or warning.

It seems like it would be useful to support current Matlab behavior because this syntax has probably been used in 25 years of m-file code.

Related bugs (resolved) are bug #31615 and bug #49759.
