Subject: [PATCH] Fix "./truncate -s 1e2" to say "not integer" instead of "too
 large".

It's not scientific notation, it's "exabyte suffix" and then the check
for trailing 'd' meaning decimal instead of binary always incremented past
the non-null character whether or not the test matched, so the error
check at the end didn't catch a non-d second suffix.
