Comment (by duncan):

 Replying to [comment:1 NeilMitchell]:
 > FWIW, I considered the user vs system %PATH% split, but when I was
 having problems I checked and all my copies of haddock were on the user
 part of %PATH%, so that doesn't seem relevant.

 Yeah, same here.

 I note that we do not pass the `%PATH%` to the `SearchPath` function. We
 pas `NULL` which lets it do some system-dependent thing. It might be
 interesting to see if passing the `%PATH%` makes any difference to the
 behaviour. A quick google search doesn't bring up anything about this
 oddity.
