Hmmn, OK. I *did* read dot-courier(5), from head to toe, and am looking at it now, again. All I saw was
RUNNING AN EXTERNAL PROGRAM Lines that begin with a single | character run an external program. The rest of the line specifies the command to be executed by the shell. Long commands can be continued on another line by terminating the previous line with the \ character.
I was assuming that I needed the single-quotes in there to protect the double-quoted environment variables, but I guess not.
You do need it.
But NOT before the | character itself.
It clearly says that "lines that begin with a single | character", and not the ' character.
Furthermore: "the rest of the line specifies the command to be executed by the shell".
Therefore, if you need apostrophes to protect environment variables in the shell command, then that's where you stick them.
