builtin: Reject malformed printf specifications with digits after '*'
Dash doesn't notice when a format string has digits following a * width
specifier.
$ dash -c 'printf "%*0s " 1 2 && echo FAIL || echo OK'
%10s FAIL
$ bash -c 'printf "%*0s " 1 2 && echo FAIL || echo OK'
bash: line 0: printf: `0': invalid format character
OK
$ mksh -c 'printf "%*0s " 1 2 && echo FAIL || echo OK'
printf: %*0: invalid conversion specification
OK
With this patch dash complains about the malformed specifications.
$ ./src/dash -c 'printf "%*0s " 1 2 && echo FAIL || echo OK'
./src/dash: 1: printf: %*0: invalid directive
OK
