Display of strings by interpreter

[Rik]

All,

Continuing with the theme of how results are displayed in Octave, should we
move to displaying char arrays and strings with enclosing single or double
quotes?  This is how Matlab behaves, and I think it may be useful to
understanding when there are trailing spaces or null characters.

Current behavior with Octave

octave:1> "Hello World"
ans = Hello World

Current behavior with Matlab

"Hello World"
ans = "Hello World"

'Hello World     '
ans = 'Hello World     '
strtrim (ans)
ans = 'Hello World'
