Good points, both.  Here's take 2, and I'm sure any remaining bugs can be
smoothed out by those interested in using it.  This version _will_ replace
special characters with escaped versions (you have to replace \ before ",
this was tripping me up for a while) and return them to original upon
uncommenting; it will also not uncomment a line unless it is in fact a
comment.

if (!(who = this:loaded(player)))
  player:tell(this:nothing_loaded_msg());

  player:tell(range);

  player:tell("Junk at end of cmd:  ", range[3]);

  v_name = verb[1] == "c" ? "comment" | "uncomment";
  for i in [from = range[1]..to = range[2]]
    line = this.texts[who][i];
    if (v_name == "comment")
      line = strsub(line, "\\", "\\\\");

      this.texts[who][i] = tostr("\"", line, "\";");
    elseif (line[1] == "\"" && line[$ - 1..$] == "\";")
      line = strsub(line, "\\\\", "\\");
      line = strsub(line, "\\\"", "\"");
      this.texts[who][i] = line[2..$ - 2];

"Finished.
