configure --docdir ignored?

So as I'm working on the freebsd port I noticed that --docdir= is  
being ignored in favor of datadir.  In fact, this appears to have been  
true for some time, since it has been in the port as far back as I  
have local copies (2.1.17 or thereabouts)

The patch in the port is

                 @${REINPLACE_CMD} -e '/^docdir/s!=.*!= @docdir@!'\
                                   ${WRKSRC}/docs/Makefile.in

This changes the following -- which frankly, seems like the right  
thing to do.  If someone supplied a --docdir on the configure line,  
why aren't we using it?

176c176
< docdir = $(pkgdatadir)/doc
---
 > docdir = @docdir@
