vim-patch:9.1.0913: no error check for neg values for 'messagesopt' (#31511)

Browse Source 
Problem:  no error check for neg values for 'messagesopt'
          (after v9.1.0908)
Solution: add additional error checks and tests (h-east)

closes: vim/vim#16187

65be834c30

Nvim's getdigits() checks for overflow, so the code change isn't needed.
