--- Begin Message ---Hello, although this behaviour is not optimal, it is accepted by the POSIX specs, so it will not be changed upstream. checkbashisms already warns against the use of `$((--n))`: possible bashism in line 1 ('$((--n))' should be '$((n=n-1))'): Regards, -- Gioele Barabucci <[email protected]>
