Subject: Fix buffer_getchar to only error if we'd exceed the buffer size
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/f93d57195dfa072ca6fea0c76428fde5337bcabc?hp=f93d57195dfa072ca6fea0c76428fde5337bcabc

Fix buffer_getchar to only error if we'd exceed the buffer size

  We were erroring when we retrieved the end of the buffer, and not
  if we overflowed past the end. Check if we'd overflow and return
  an error only in that case.
