 > Patch doesn't look complete — if the pattern fails, it'd also return a
 string ( `ltrim( $text )` ). We should make it as consistent as possible.

 Looking at my comment above, I think this was indeed half a patch, as I
 wasn't sure what could / would be broken when potentially doing something
 with that left trim, so I just handled the simple case at the time.
