Telling if options were set correctly in 7.1?

With 7.0.3, the file "postmaster.opts" listed the options
with which the postmaster had been started.

However, with 7.1 and the new "postgresql.conf" file, any
options set via that file are not listed in "postmaster.opts".

I like the warm, cozy feeling from knowing that the
options set in "postgresql.conf" have, indeed, been
applied.  What's the easiest way to check this?

Thanks!
