Comment(by nickm):

 I tweaked it in branch continuation in my repository.

 I think, among other things, I removed a condition where we could run off
 the end of the string.  When you did:
 {{{
  } else if (*line == '#') {
    do {
      ++line;
    } while (*line && *line != '\n')
  }
  ++line; // OOPS
 }}}
 consider what would happen when the last line in the file had a comment
 with no newline at the end.  The loop would continue until *line=='\0',
 and then the second increment (marked "OOPS" above) would advance the line
 one more character.  Ouch!

 And a completely cosmetic thing: It seems odd to day "Implements bug
 1929".  Implementing a bug sounds like you're putting it _into_ the code.
 Since this is really a feature rather than a bugfix, I'm going with
 "resolves bug 1929", but "resolves ticket 1929" would also sound ok to me.
