target misc: help/usage updates

Provide helptext which was sometimes missing; update some of it
to be more accurate.

Usage syntax messages have the same EBNF as the User's Guide.

Don't use "&function"; functions are like arrays, their address
is their name.  Shrink some overlong lines; remove some empties.
