Details:

This is just an oddity, and I'm not sure it has any relevance.

When concatenating a double-quoted string with a number the result is a
single-quoted string.  However, I suspect the rationale is that double-quoted
string + ! double-quoted string = single-quoted string.

Thus, adding a single-quoted string, or a number counts as a non-double-quoted
string and the result is therefore a single-quoted string.


octave:1> x = ["ab" 99]
x = abc
octave:2> is_dq_string (x)
ans = 0
