Well, the change is essentially to G_parser() and G_gui(), so it would
automatically affect everything which uses those functions.

However, fixing startup bugs/misfeatures (e.g. ensuring that programs
don't write to stdout prior to calling G_parser()) would become that
much more critical. It's already an issue for e.g. --html-description,
but bugs in generating the HTML documentation are less critical than a
bug in the UI.

Also, programs which don't use G_parser() (e.g. r.mapcalc) will
typically need special treatment (e.g. r.mapcalc explicitly traps the
"r.mapcalc help" case, although it doesn't handle any of the others). 
Maybe we need a "minimal" alternative to G_parser(), which just traps
--help, --html-description etc, but doesn't do option parsing.
