strings that contain characters where the LSB is numeric but the MSB
is non-zero.  Ticket [689137afb6da41]

c02a43afae Only require double-zero terminators on database filenames, not any every 
files supplied to the xOpen method.  This backs out [2544f233f1].  Also
refactor the fillInUnixFile() routine in os_unix.c to reduce the number
of parameters.
