Ticket #3047: fix mc arguments handling.

Browse Source 
Following cases from command line are possible:
  * 'mc' (no arguments):
     active panel uses current directory
     passive panel uses "other_dir" from ini
  * 'mc dir1 dir2' (two arguments):
     left panel uses dir1
     right panel uses dir2
  * 'mc dir1' (single argument):
     active panel uses current directory
     passive panel uses dir1
