Bug description: natsort ignores extra white space
Description:
------------
natsort (and related functions like strnatcmp) appear to
collapse all white space chars into just one space, so
that 'a a' sorts at the same level as 'a a' (so the
order of the returned sort is not determined), while it
should sort one before the other (which one is more
"natural" is up for discussion, but it shouldn't
randomly return one or the
other).
Reproduce code:
---------------
$array = array('a b','a a','a a','aa','a b','ab');
natsort($array);
echo "<pre>";
foreach ($array as $val)
echo "$val\n";
echo "</pre>";
Expected result:
----------------
Should print:
aa
ab
a a
a b
a a
a b
-OR-
aa
a a
a a
ab
a b
a b
Actual result:
--------------
Actually prints (changes order if you change order in
array definition):
aa
a a
a a
ab
a b
a b
