I don't mind.

Logically, it wouldn't be the same. In your case, "*ptr++ = '\n';" will
be executed, regardless whether !((gp-1)->mode & ATTR_WRAP)) holds true
or not (assuming x == 0).
Whereas in Roberto's case, the if condition never holds true for x == 0.
So as you mentioned, the outcome for x == 0 is different. It is to
decide which one is the correct behaviour.

As I my mentioned, a quick test of my fix (which should be logically
equivalent to Roberto's fix) showed no problems, but then again, it was
just a quick test.
