of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

    was having its last element zero'd.  It turns out not to be a security
    hole or to have any real effect on the code because 'from' was previously
    pointing to a buffer of the same size as 'fromb', and the last
    element in fromb is already 0 anyway due to the use of sizeof(fromb)-1
    in the strncpy() call.  But I'm not pressing my luck so only the type-o
    is being fixed.

with remote hosts feeding it, so that some hosts have their header
pages supressed and some don't.  This is because lpd doesn't know
how to rewrite a print job before forwarding it to a remote lpd.
In particular this causes problems with p rinters that contain
their own lpd, eg. HP jet direct cards, because they can't suppress
headers.  It's not possible to have headers supressed by putting
'sh' in any printcap in the lpd chain, it is up to the originating
lpr to have a '-h' option specified at run time.

Lpr has been modified to allow _it_ to honour the 'sh' flag in the
local print cap.  This allows the administrator to switch off
headers for a particular printer (on a particular host) irrespective
of whether that printer is local to the machine or remote.

This doesn't break anything, because in the case of a remote printer
the 'sh' flag would have had no meaning, in the case of the local
printer it would have been on anyway.
