I had left out aclocal.m4 on the "use this order" line as I didn't think it'd
ever need to be changed.  Someone ("ssen" -- looks like Doug forgot to update
a chroot() passwd file again) added it, but in a separate sentence.  That
doesn't really make sense -- added it to the main sentence.

Also changed my note that none of the mailing lists require you to be subscribed
to post -- not true.  As I originally thought, the exmh ones do require that --
the bounce messages were just slow in coming.
