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.
