Internal functions

[Rik]

All,

I'm trying to update the documentation to include all user-visible
functions.  The following functions are not in the manual, but do not have
the internal '__' prefix and suffix.

db_next_breakpoint_quiet
have_window_system
open_with_system_app

Does anyone have an objection to making these internal functions?

I also notice that

help open_with_system_app

 -- Loadable Function:  __w32_shell_execute__ (FILE)
     Undocumented internal function.

So the documentation name is wrong and it sure looks like this is meant to
be an internal function.
