I had to make this same change to lpr at RPI to get "things" to work
right on some other (non-freebsd) platform, though I did it so long
ago that I don't remember what the problem was. I have some other
signal-related changes in RPI's version that I intend to merge
into freebsd too, but I'll put this change into freebsd-current
by itself.
I have wondered why I needed that on other platforms but freebsd
didn't seem to need it... Thanks!
