Follow-up Comment #2, bug #49573 (project octave):
I couldn't help myself, I was curious, and the relevant change is the one that
added support for octal escape sequences in double-quoted strings in version
3.8.0.
In old versions of Octave,
>> "\033" == char ([0, 0x31, 0x31])
ans =
1 1 1
this double-quoted string contains three characters, a NUL byte, and two 3s.
In recent versions of Octave (starting with 3.8.0), this is parsed as an octal
escape sequence. The cprintf.m script you pointed to makes use of this to
build its terminal escape sequence strings.
