Today I was troubleshooting a segmentation fault and had occasion to
run the “ps -fC troff” command. I also had to run
“gdb ./build/troff ./build/core”. Here is some filler: XXXXXX

In the foregoing, the spaces in "ps -fC troff" do not participate in
adjustment, which leads to somewhat jarringly large inter-word gaps on
the rest of the line.

I mean that it "\ " can be difficult to recognize in practice; you
_have_ to quote it or describe it somehow or the syntactically
significant space (to roff) gets lots among the regular word-separating
spaces in prose.
