Applied with minor changes:

* I thought it better to call the switch --with-wal-blocksize than
--with-xlog-blocksize.  Although we've not been terribly consistent
about it, there is more user-facing documentation that calls it WAL
than XLOG.

* I added a --with-wal-segsize switch as well.

It's not totally clear what the allowed ranges of the settings should
be.  The method of using a shell "case" to verify the setting validity
is kinda klugy, but I couldn't offhand think of a direct test for
"is this a power of 2" at the shell level, so it seems we need to be
