BUG: fix httplog trailing LF
commit a1cc3811 introduced an undesirable \0\n ending on HTTP log messages. This
is because of an extra character count passed to __send_log() which causes the LF
to be appended past the \0. Some syslog daemons thus log an extra empty line. The
fix is obvious. Fix the function comments to remind what they expect on their input.
This is past 1.5-dev7 regression so there's no backport needed.
