Title:
  Completions should be paged through PAGER when `page-completions` is
  off

Status in bash package in Ubuntu:
  Confirmed

Bug description:
  When tab completion sends output through a pager, it seemed to use
  more. Because less is better than more, I wanted it to use less
  instead, particularly so I can scroll in both directions.

  I initially made /bin/more a symlink to less (which would trigger its
  more-emulation mode, but that's still better than actual more), but
  this had no effect. As a result, I consulted the man page for bash. In
  the section on readline, there is a setting `page-completions` which
  says that when on (the default), readline will use a built-in more-
  like pager to page the results. This doesn't specify what happens when
  it is turned off, but I expected that instead of the built-in pager,
  it would use an external on, specifically the one specified in the
  PAGER environment variable. However, it instead simply dumps the
  results in the terminal.

  Please add some way to use PAGER as the pager for completion results.
