 Looking at the patch, it appears to remove some deliberate checks.  CC'ing

 Text.Printf.printf has a bug where it doesn't like negative numbers for *
 modifiers:

 {{{
 Prelude Text.Printf printf %*sx\n (-3) hi
 hix
 }}}

 In the C printf, this would be
 {{{
 hi x
 }}}

 From looking at the source, it's a pretty easy bug to fix.  Patch
 attached.  I also included a patch to turn the mixed tabs and spaces into
 just spaces since I hate that stuff.
