tests: clean up a bunch of pager testing that is about to be invalidated

All this attend logic and potential bugs just no longer make sense to test.

 Enable ui.formatted because pager won't fire without it, and set up
 pager and tell it to use our fake pager that lets us see when the
 pager was running.

 If 'log' is in attend, then 'history' should also be paged:

 Pager should not start if stdout is not a tty.
 
   $ hg log -l1 -q --config ui.formatted=False

 Pager with color enabled allows colors to come through by default,
 even though stdout is no longer a tty.

 Pager works with shell aliases.
 
   $ cat >> $HGRCPATH <<EOF
   > [alias]
   > echoa = !echo a
   > EOF
 
   $ hg echoa
   a
   $ hg --config pager.attend-echoa=yes echoa
   paged! 'a\n'
 
 Pager works with hg aliases including environment variables.
 
   $ cat >> $HGRCPATH <<'EOF'
   > [alias]
   > printa = log -T "$A\n" -r 0
   > EOF
 
   $ A=1 hg --config pager.attend-printa=yes printa
   paged! '1\n'
   $ A=2 hg --config pager.attend-printa=yes printa
   paged! '2\n'
 
 Something that's explicitly attended is still not paginated if the
 pager is globally set to off using a flag:
   $ A=2 hg --config pager.attend-printa=yes printa --pager=no
   2
 
 Pager should not override the exit code of other commands
 
   $ cat >> $TESTTMP/fortytwo.py <<'EOF'
   > from mercurial import cmdutil, commands
   > cmdtable = {}
   > command = cmdutil.command(cmdtable)
   > @command('fortytwo', [], 'fortytwo', norepo=True)
   > def fortytwo(ui, *opts):
   >     ui.write('42\n')
   >     return 42
   > EOF
 
   $ cat >> $HGRCPATH <<'EOF'
   > [extensions]
   > fortytwo = $TESTTMP/fortytwo.py

   $ hg fortytwo --pager=on
   paged! '42\n'
