jilles e3bbdad108 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.
