Typo in allout.el rev. 1.73?

[Giorgos Keramidas]

Hi Stefan and all,

Part of the 1.73 changes in lisp/allout.el includes:

% @@ -292,7 +301,7 @@
%  Set to the symbol for either of `allout-mode-leaders' or
%  `comment-start' to use only one of them, respectively.
%
% -Value nil means to always use the default \(`.').
% +Value nil means to always use the default \(`.').t
%
%  comment-start strings that do not end in spaces are tripled, and an
%  `_' underscore is tacked on the end, to distinguish them from regular

Was the additional t intentionally added here?
