I'll try to figure it out, but maybe after the code freeze.  I started
my programming career writing curses software a million years ago on a
couple of extinct Unixes... I might even be able to remember how it
works.  This is not a problem for committing the PSQL_WATCH_PAGER
patch, I just mentioned it here because I thought that others might
try it out on a Mac and be confused.

Commits

  1. Fix \watch's interaction with libedit on ^C.

  2. Add PSQL_WATCH_PAGER for psql's \watch command.

  3. psql: Show all query results by default

  4. Add a comment warning against use of pg_usleep() for long sleeps.
