[PATCH 2/3] lei: rearrange OPT_DESC and drop some TBD switches

[Eric Wong <e@80x24.org>]

It'll be easier for us to have the option-spec in front of the
command instead of the other way around.  The option-spec in
front makes it easier to sort and keep track of potentially
confusing/ambiguous use of command-line switches between
different commands.

We'll also update some of the proposed switches while we're
at it.
