• [x] very long wrapped line, with multiple single line matches (#58)
  • indicator just stays at the start of the line, it should follow the matches as they wrap
• [x] very long wrapped line, with one or more matches (#58)
  • selecting the first match just places the indicator at the start of the line, it should be on the line where the match is
  • selecting subsequent matches only works if they're multiline matches, otherwise the indicator stays at the start of the line
