Witness the following code:

printf( "PHP Version=%s\n", phpversion() );
print "Output should be [abc] in all cases\n";

$masks = Array( "%-3.3s", "%.3s", "%-.3s" );
$str = "abcdefg";
foreach ( $masks as $mask ) {
    printf( "[$mask] <-- %s\n", $str, $mask );
}

Under 4.2.3 we get:
PHP Version=4.2.3
Output should be [abc] in all cases
[abc] <-- %-3.3s
[abc] <-- %.3s
[abc] <-- %-.3s

Under 4.3.0 we get:
PHP Version=4.3.0
Output should be [abc] in all cases
[abcdefg] <-- %-3.3s
[abc] <-- %.3s
[abc] <-- %-.3s

This breaks a TON of column-formatting code for our application.  We're reverting to 4.2.3 until this is fixed.

The test suite in ext/standard/tests/general_functions/001.phpt does not test that specific combination of width & precision.
