Partially reverts aac842439f and fixes the
underlying issue that led me to throw that together: the issue was that
the check_line_lengths function needed to add 2 to the index otherwise
iterations after the first would over-estimate the length of the
currently found line by 2, because the prior index included the CRLF
that it found in the input.
While poking at this, I found that there was a fairly harmless edge case
around non-DATA line handling: we used a 1024 stack buffer to read the
command in, and would accept anything that fit into that as valid, even
though the limit is set to a slightly smaller value.
