The most elegant way avoids fiddling with boxes, but is counterintuitive
(elegance = counterintuitiveness very often in TeX!!)

\leftskip=0pt plus1fil \rightskip=-\leftskip % these cancel on most lines
\parfillskip=\leftskip \multiply\parfillskip by 2 % or \parfillskip=0pt plus2fil

I think I first heard this from barbara beeton.

Take the definition of \@makecaption from the appropriate style file,
put \begingroup and the two lines above at the very beginning; put
\endgroup at the end.
