It wasn't until this thread that I became aware of `pr` as I've been an 
`nl` user for years.

It wasn't until the message that I'm replying to that I realized the 
naming relation between `pr` and `lpr`.

I also wonder if `pr` makes more sense in the context of teletypes 
wherein when you `pr`(int) a file, you end up with a printout on the 
teletype that you're using.  Conversely `lpr` would send something to 
the line printer elsewhere.

It makes sense in my head.

I have no idea if it's accurate or not.
