Ticket #1656: Incorrect processing of cases the lack of rights to save preferences.
In the case where insufficient rights to the contents of the directory ~/.mc/* to
save preferences I get "settings saved in ~ /.mc/ini", but really nothing is saved.
It would be correct to issue a message like "Not enough permissions to save the ~/.mc/ini"
Also, when autosave should be issued a message about the lack of rights.
This branch will check rights of config-files.
testCase:
*) chmod 0400 ~/.mc
*) run mc
