0151       fish interprets closing parenthesis inside comments as end of command substitution, if the comment starts
0152       inside of a command substitution!
0153
0154       fish does not interpret them this way, when
0155         they are escaped by a \ or
0156         they are matched by an earlier opening parenthesis inside the same comment.
0157       This behaviour is replicated here.
0158
0159       Command substitutions may span several lines, so the closing parenthesis may be on a different line,
0160       than the opening one. In the interactive shell you need a continuation line for this, not so in scripts.
0161       Blocks of code with multiline command substitutions may be commented out. This should not lead to visual artifacts.
0162
0163       There is one case, where the following solution fails: a lonely closing ")", which is marked as an error.
