When I press F1 in DrRacket, I get a nice new browser tab with search
results from ~/.racket//doc/ directory.
I would like to have a thing like this for my custom non-sexp language.

There could be something wrong with `scheme_get_long_long_val`, but
it's surprising that it could go wrong in a machine-specific way.
