Summary: \rightmarginkern doesn't work for last lines 
Category: hz
Group: None
Resolution: Accepted


Initial Comment:
% Protrusion works fine even for the last line of a paragraph. 
% If, however, you ask \rightmarginkern, it will always report
% zero margin kerning.
\pdfprotrudechars2
\rpcode\font`\. 200
\parindent0pt
\parfillskip=0pt
\hsize50pt
\tracingoutput1
\showboxbreadth\maxdimen
\showboxdepth\maxdimen

correct:
\setbox0\vbox{AAA AAA. AAA AAA.}
\unvcopy0

wrong:
\newbox\splitbox
\newdimen\rmarg
\loop\ifvbox0
  \setbox\splitbox\vsplit0 to\baselineskip
  \unvbox\splitbox\setbox\splitbox=\lastbox
  \rmarg\rightmarginkern\splitbox
  \unhbox\splitbox\kern\rmarg\rlap{ : \the\rmarg}
\repeat

\bye
