Fix off-by-one error in \fad, \fade
Typical greater vs. greater-or-equal case. This especially fixes fades
with zero delays. A zero delay in the two-argument form means no fade at
all, but previously this faded over a single frame, since the code used
"greater" semantics, while "greater or equal" is required here.
Notably, this avoids blinking/flickering in some tightly timed karaoke
scripts.
