It doesn't. It looks at ${DOCSDIR}. See add-plist-docs target in
Mk/bsd.port.mk.

As such the requirement for this to work, is that docs are installed in
${DOCSDIR}. If a port has a valid reason to not install documentation
into ${PREFIX}/share/doc/${PORTNAME} then DOCSDIR should be set in the
port's Makefile.
Same applies to PORTDATA and PORTEXAMPLES and their respective DATADIR
and EXAMPLESDIR.

I think even more space can be saved if a PORTWWW is introduced, though
PORTWWW=* should be used more carefully as WWWDIR can be dynamic.
