Not quite sure I followed your explanation, which means it's difficult
for me to propose an alternative wording.  Maybe:

Add an assert here to make it obvious that the prior loop consumed the
rest of the input, and that all further code in the function is focused
on output.

On the other hand, if you are okay with it, I wouldn't mind squashing
the first and second patches into one (as the first patch is then easier
to read when it is obvious that we used the wrong length variable).  But
until I get your feedback (on either squashing the two patches or
tweaking the wording), I'm just placing your patches as-is on my NBD
queue for inclusion prior to rc0.
