As I was looking at this I wondered if there might be anywhere else that
needed adjustment. One thing that occurred to me was that that maybe we
should replace the use of "-w" in pg_regress.c with this rather less
dangerous flag, so instead of ignoring any white space difference we
would only ignore line end differences. The use of "-w" apparently dates
back to 2009.

Thoughts?
