I'm having trouble using spaces as replacement text while using $regsubex (Awesome addition by the way)

Code:
//echo -a $!regsubex: $regsubex(+ab,/([+])/,\1 $chr(32)) | /noop $regsub(+ab,/([+])/,\1 $chr(32),%x) | echo -a $!regsub: %x

gives:
$regsubex: +ab
$regsub: + ab

Is this a bug or am i doing something wrong here ?
