BusyBox ash as subshell for mc (midnight commander)?

[re-send to list because reply-to header was wrong as usual]

Sorry, I wanted to send my message to the list, but the reply-to was
wrong - it has been annoying me for a long time on that list. Depending
on who answers the messages, you have to be careful to use "reply to
all". :-(

Anyway, fancy prompt is active and does not help. To use full desktop
settings is not an option in my embedded environment. I would appreciate
if you found out what exactly needs to be configured in BB or patched in
MC in order to get this to work.

Thanks in advance
