 New Revision: 193636
 URL: http://svn.freebsd.org/changeset/base/193636
 
 Log:
   Mention the range for the exit status for the exit special builtin.
   
   The exit status may exceed 255 in some cases (return); even though it seems
   unwise to rely on this, it is also unwise to assume that $? is always
   between 0 and 255.
   
   This resolves bin/124748 by documenting that 'exit -1' is not valid.
