Re: BUG #11986: psql uses pager inside Emacs shell buffer (not a terminal)

Right.  It only matters when we think stdout is a tty.

withTERM=dumb. Decades ago that would have meant a teleprinter terminal (or, perhaps, some ancient serial terminal or
Minix1.0). Nowadays it means running inside emacs or some other management program, so there is no need to run a pager. 

I am pretty hesitant about extending the emacs example to apply to *every*
context where TERM=dumb, especially given the complete lack of field
complaints in this area.  I'm good with putting in a special hack for when
we're sure we're inside emacs, but I don't think an adequate case has been
made for assuming TERM=dumb means the opposite of what it appears to mean
on its face.  Especially not if there won't be a way for the user to
override the choice.
