to be honest I'm not overly enthusiastic about the idea.
partially from the mess we had when we tried it with g.region
before.

It's hard enough to know now when a module will really do
anything different when using the --verbose flag (most do the
same but some give really important info with it) which is
advertised for all modules. you'd just have to guess when an
option had a shell-style version programmed in.

[maybe add a new module->has_verbose, module->has_shell module
init flags?]

if using two dashes you might as well use a word, not the
meaningless "-g". eg --script-style.

and only for grass7 if it does happen.
