The original:

.if !defined(NOPORTDOCS)
OPTIONS+=       REFDOCS "Install the reference documents" on
.endif
.if !defined(NOPORTEXAMPLES)
OPTIONS+=       EXAMPLES "Install the example code" on
.endif

.include <bsd.port.options.mk>

So if the user has set NOPORTDOCS in make.conf, that option does not 
appear in the dialog.  Likewise with NOPORTEXAMPLES, and if both are 
set, the dialog does not appear at all.

If either docs or examples are allowed, the user gets the chance to turn 
them off for this port.
