} The problem here is we don't know how many parameters the themes
If the theme doesn't work with zero parameters, it's broken. If there is
no preview function, don't try to guess at parameters; preview whatever
the defaults are.

If you want a description that isn't meant to be displayed as-is, add
another one; don't overload use of the help function.
See prompt_bart_help in prompt_bart_setup for a good reason why not.

} Maybe you mean making color schemes independent of specific themes?
No, he means exactly what he said. There are some fonts that have half-
tone special characters, and some of the themes rely on those fonts to
get a "fade" effect from one color to another.
} One problem I noticed the other day is if one prompt sets PS3, PS4, or
} RPS1, then those vars won't get reset when changing prompts, even when
} setting the prompt to "off".
It's a general shortcoming that themes only change the parts of the prompt
that they're interested in; "off" is just another theme with a silly name.
To really have "prompt off" mean what it seems to mean, the theme system
would have to save and restore the original values of all the variables.
} There do seem to be some problems with the distributed themes descriptions
} too, for example adam1 (correct me if I'm wrong) says it requires an 8 bit
} font when it doesn't.
The usual case of the doc not keeping pace with other changes. It did
require an 8bit font at one time.
