Yes, I found that one myself. My old ftplugin/haskell.vim used to
have autoindent set, but importing your haskell mode overwrote that
(slightly irritating behaviour if you ask me ;-). Putting my old
config into ftplugin/haskell_mine.vim restored the behaviour.

These are my g:haddock_ setting:
let g:haddock_browser_callformat = "%s %s &"
It's on a Debian system, hence the use of x-www-browser. I've tried
using both epiphany and iceweasel directly as well, with exactly the

That is what I have in mine as well (though it's located in
/usr/share/doc/ghc6-doc/libraries/). I'm not really sure where the
extra level of encoding comes from.

My Vim-scripting fu is minimal. Do you have any pointers on how to
set breakpoints, step, and inspect variables?
