Bug description:  mismatch between sscanf and localeconv

Description:
------------
sscanf() seems not to be locale-aware when interpreting '%f', even though
the documentation says it is. localeconv() says that after my call to
setlocale(), the comma is interpreted as decimal separator. Still
everything after the comma is omitted.

Tested environments:
Windows XP, PHP 5.2.5, Apache 2.2.8 (mpm_winnt)
Linux 2.6.9, PHP 5.2.6RC1, Apache 2.2.8 (prefork)

Reproduce code:
---------------
setlocale(LC_ALL, array('de_DE.utf-8', 'german'));
$value = sscanf('3,14159265', '%f');
echo '<div>parsed: &pi; &asymp;', $value[0], '</div>';
echo '<div>formatted: &pi; &asymp;'; printf('%f', 3.14159265); echo
'</div>';


Expected result:
----------------
parsed: &#960; &#8776;3.14159265
formatted: &#960; &#8776;3,14159265

Actual result:
--------------
parsed: &#960; &#8776;3
formatted: &#960; &#8776;3,14159265
