 Bad.hs:
 {{{
 -- | test
 --
 -- @
 --     nbsp_c2_a0 = " "
 -- @
 module Bad where
 }}}

 Good.hs:
 {{{
 -- | test
 --
 -- > nbsp_c2_a0 = " "
 module Good where
 }}}

 Be careful: " " is ont "\x20", but "\xC2\xA0" in both cases.

 Haddock fails to parse Bad.hs, but works on Good.hs:
 {{{
 [sf] /tmp/y:haddock --html src/Good.hs src/Bad.hs
 Haddock coverage:
 haddock module header parse failed: Cannot parse header documentation
 paragraphs
    0% (  0 /  1) in 'Bad'
  100% (  1 /  1) in 'Good'
 }}}

 Found in haddock-2.13.2.1.

 Originally if was found in directory-layour source.
 Hackage parses it, but not local haddock:

     http://hackage.haskell.org/packages/archive/directory-
 layout/0.4.0.0/doc/html/System-Directory-Layout-Traverse.html

 Thanks!
