wrong return from panelize if panelized in both panels

[newbie-02]

perform a search in one panel, panelize the search,
starting from another directory do the same in the other panel,
switch back to the first panel, if you leave the view by the '..'
at the top of the list you come back to the directory where you
started the second search.

Currently by design MC saves only one panelization result. Second panelization clears result of first one.

Yes, I agree than each file panel should have own buffer for panelization.
