Automatic Indentation of Comments in Lisp Mode

[RICH at MIT-AI (Charles Rich)]

I would like to suggest the rule that a comment on an otherwise blank
line be indented by default the same as code would be on that line, i.e.
control-; and tab should be the same on an otherwise blank line. For example

	(LET (..)
	  (...)             ;out here for comment on same line as code
          ;in here for comment on blank line
          (FOO ...))

and of course M-C-Q would obey the same rule.

	Thanks, Chuck Rich.
