Dan, I think you did find a problem, but single-quotes are needed.

From Matlab

strjoin({'Octave','Scilab'}, '\n')

ans =

Octave
Scilab

From Octave

strjoin({'Octave','Scilab'}, '\n')
ans = Octave\nScilab

So the second string needs to be escaped.

What about the first?  Trying Matlab again..

strjoin({'Octave\n','Scilab\n'}, 'foo')

ans =

Octave\nfooScilab\n

No. Only the second string.

So a patch that implements ..

        strjoin({'Octave','Scilab'}, do_string_escapes ('\n'))

... should do the job.
