% The lastparline or the parfillskip solution is overkill in many
% places. It is optimal for larger paragraphs, but creates too much
% strech in every other case, particulary not in the main text, such as
% the TOC and so on.
%
% It can be useful with a limited scope, but for general application it
% becomes more of a problem to check where it has gone too far in
% adjusting line breaks.

% lastparline:
%   ``Ensures that the last line of a paragraph is at least as long as the
%   double value of \parindent. When LuaTEX is used, the solution provided
%   by Patrick Gundlach is used. With other rendering engines, it is the
%   native solution provided by Enrico Gregorio that serves as an
%   implementation.''
