I personally find that this "ret < count" that comes after checking
if ret is negative expresses what it is checking in a more natural
way than "ret must be exactly count".
It is not a big deal, as either one needs to be read with an
understanding that read_in_full() would read at most "count" bytes
to see if the right condition is being checked to declare
"truncated" anyway. But I somehow find
ret = read up to count
if (ret < 0)
read failed
if (ret < count)
we failed to read as much as expected
a bit more natural.

Likewise, even though it is harder to see that this follows another
explicit check for "ret < 0".
Thanks.
