Remove unnecessary iteration variable in inline.
-       for (i = 0; i < in; i++) putchar(' ');
+       for (; in > 0; in--)

while(in--) putchar(' ');

That goes into an infinite loop if the argument is negative because
it emits a cmpl $0, x(%ebp).  Should never happen, but there's no
reason not to prevent it with a for loop.

while (in-- > 0) putchar(' ');

still shorter :)

Why do we keep talking about a usually ifdef'ed out debugging
section?

I'll be removing that section altogether ;-).
