An invalid pager command name is reported sensibly if we don't have to
use shell=True in the subprocess call:
  $ hg log --limit 3 --config pager.pager=this-command-better-never-exist
  missing pager command 'this-command-better-never-exist', skipping pager

  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     modify a 10
  
  \x1b[0;33mchangeset:   9:6dd8ea7dd621\x1b[0m (esc)
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000

A complicated pager command gets worse behavior. Bonus points if you can
improve this.
  $ hg log --limit 3 \
  >   --config pager.pager='this-command-better-never-exist --seriously' \
  >  2>/dev/null || true
