sort and expand the prunelist in a more or less generally sensibly

order.  Put some strategic comments in about how much storage is
necessary and a longer explanation on the top.

It is now pretty trivial to put nanoBSD on as little as a 64MB CF card.

+# Depending on the size of the storage device you use you may have to
+# remove features you do not need in order to fit.
+#
+# Here is a list of candidates which you can edit and rearrange as
+# you see fit.  Well, almost: A few of these options depend on each 
+# other, but you will find out about that sooner or later.
+#
+# You can save a couple of megabytes by building a kernel where you
+# remove all the stuff you do not need (the 9 different raid controller
+# device drivers, drivers for old ISA network cards etc).
+#
+# I have inserted comments along the way which says how much storage
+# is necessary in a code partition if you comment out the lines
+# *above* but leave uncommented the lines *below* the comment.
+#
+# Your storage media needs to be a bit larger than twice as large as
+# the number in the comment in order to leave space for the config 
+# partition and boot code.  Also remember that any ports/packages you
+# install will need space as well.
+#
+# Remember to set the physical disk parameters in Makefile.

+# Other untested candidates for removal:
