which got limited to at most two tries 26 years ago for the 2.3 release,
but the documentation was never updated to match this change. Do it now.

Add ability to limit memory presented to kernel with
'machine memory =128M' style commands. Thanks to
phessler for finding a small man page niggle. Bumped
version strings to a nice round fraction, and make them
the same across the board. Easier to identify boot
binary versions that way.

A similar change will be made to amd64 boot soon.
