If I use something like

lp:\
        :lp=:rm=remote.machine:rp=printerqueue:\
        :sd=/var/spool/lpd:\
        :lf=/var/log/lpd-errs:\
        :if=/usr/local/bin/pfilt:\
        :mx#0:sf:sh:rs:

it seems that the data isn't going through pfilt at all (pfilt doesn't
get run) but sent to the remote printer as-is.  Is this a bug or a
feature?  I think it's either a bug or I'm doing something stupid.

Besides, if you have a comment in /etc/printcap ending with backslash,
it seems to confuse lpr/lprm/lpq.  This _is_ a bug, isn't it? ;)
