Fix rlist argument check
schnapps rlist
is the same as schnapps list
in that it takes no mandatory arguments by default, and optional arguments for changing the listing output format (https://gitlab.nic.cz/turris/schnapps/-/blob/master/schnapps.sh#L86-94). However, recent changes in 5991c096 adjusted the argument check for rlist
to only work if exactly 1 arg is provided.
This MR adopts the same argument check for list
, erroring if more than 1 argument is provided, allowing schnapps rlist
to work without arguments.
