Since 'shift 2' when $# is 1 is an error, and results in non-zero status,
it should print a diagnostic to stderr.
So maybe the thing to do is to turn on the shift_verbose option in posix
mode.
Cool - I didn't realize we already had a shopt for that. Yes, it sounds
like in POSIX mode, shift_verbose should be turned on.
On a related note, should turning on POSIX mode also auto-enable xpg_echo?
