If I got the line

```
> { -# OPTIONS_GHC -fglasgow-exts -XTemplateHaskell #- }

```

in the documentation-part (description) of the .cabal-file I'll get the error message

```
haddock: parsing haddock prologue failed

```

when running

```
$ cabal haddock

```

but if I get rid of the `{` and `}` everything works fine. Is there some way to escape `{}` so they can be used in the description?
