      <!--
      fish interprets closing parenthesis inside comments as end of command substitution, if the comment starts
      inside of a command substitution!

      fish does not interpret them this way, when
        they are escaped by a \ or
        they are matched by an earlier opening parenthesis inside the same comment.
      This behaviour is replicated here.

      Command substitutions may span several lines, so the closing parenthesis may be on a different line,
      than the opening one. In the interactive shell you need a continuation line for this, not so in scripts.
      Blocks of code with multiline command substitutions may be commented out. This should not lead to visual artifacts.

      There is one case, where the following solution fails: a lonely closing ")", which is marked as an error.
