Neat.

Actually the command line doesn't seem to work on Mac OS X. I didn't 
complain because I know you guys have higher priorities...

But I would just say that putting it with "prothon.exe" is a bad idea. 
What about multiuser systems?

Luckily it doesn't look to me like the code does that:

if ((home = getenv("HOME")) != NULL)
     apr_snprintf(histfile, sizeof(histfile),
             "%s/%s", home, PROTHON_HISTORY);

Some day it should use Windows APIs to find the user's home directory 
(on Windows).

You can't really deal with load and save by dropping into the real shell.

That's good enough I suppose.
