trim: don't issue unnecessary warning
trim: don't issue unnecessary warning

trim would warn about not reaching the final position if the specified
end coincided with the actual end of audio, as in "trim -10 -0" (last
ten seconds of the input). This is of course unnecessary and
confusing, so don't do it.
