  -----------
  [MC] Fix accidentally eating the newline when handling a comment char at the end of the line. (#165129)

If we have a target where both # and ## are valid comment strings,
a line ending in # would trigger the lexer to eat 2 characters
and therefore lex the _next_ line as a comment. Oops. This was introduced
in 4946db15a74b761c5ac4ead18873639236b4ab5d
