    _______________________________________________________

Details:

A variable created and exported afterwards, isn't marked 'export' after a new
context was created by issuing configfile. Thus if you issue another time
configfile the variable is unset.
This means recursive menus deeper than 2 menus are not possible by loading
another configfile.

Example:
set blub=blob
export blub
configfile <file>
configfile <file>
echo $blub
=> nothing, blub was unset after the second configfile (prefix also so
everything fails).

Workaround:
In every new context (-> every .cfg file) (re)export the variable (and
prefix, root).

Attached is a patch which marks variables copied into the new context again
'export' preventing breakage of prefix and root.
