329847983274983274983274983274asdfasdfadsflkjdsalkfafds isn't a number,
so it is a syntax error.

Same here, syntax error, which makes sense too.

permit persist 2147483680 :wheel

throws a syntax error too, which is a problem.=20


To give more context, I don't set "persist" because 5 minutes is too
long for me, I'd like to enable it for a couple of seconds, typically
less than 30. This way I can type my command "doas this && doas that"
without typing my password twice, and without having to remember the
persistance.
