Actually, the only part of qed.sty that I use is this:
[EMAIL PROTECTED] set up
\parfillskip=0pt % so \par doesnt push \square to left
\widowpenalty=10000 % so we dont break the page before \square
\displaywidowpenalty=10000 % ditto
\finalhyphendemerits=0 % TeXbook exercise 14.32
%
% horizontal
%\leavevmode % not needed since we now only use it in hmode
[EMAIL PROTECTED] % this used to be incorporated
#1% % the end-of-proof mark (or whatever)
%
% vertical
\par}}% % build paragraph with the above
parameters
[EMAIL PROTECTED] horizontal
\unskip % remove previous space or glue
\nobreak % don't break lines
\hfil % ragged right if we spill over
\penalty50 % discouragement to do so
\hskip.2em % ensure some space
\null % anchor the following \hfill
\hfill % push \square to right
}%
Compare with \wordright
\def\dowordright[#1]%
{% don't change
\groupedcommand
{\removeunwantedspaces
\hfill
\allowbreak % changed back from \hskip\zeropoint
\strut
\hfill
\quad % decent spacing
\hbox}
{\doifelse{#1}\v!right{\kern-\rightskip}{\doifsomething{#1}{\kern-#1}}%
\parfillskip\zeropoint
\par}}
And there is also \signed from the texbook
\def\signed #1 (#2){{\unskip\nobreak\hfil\penalty50
\hskip2em\hbox{}\nobreak\hfil\sl#1\/ \rm(#2)
\parfillskip=0pt \finalhyphendemerits=0 \par}}
What was the motivation for \wordright? I thought it was same as
\signed in the TeXbook (pg 106). But \signed uses \nobreak
(\penality1000) and \penality50, \wordright uses
allowbreak (\penality0). And then there is \finalhypendemerits=0 which
is "missing".
And if you are relooking this macro, it will be nice to have the
\hfill configurable (dotfill or something fancier)
