haddock document generation fails for executables when a preprocessors is needed

Description

I'm coming to think I'm the only one who tries to generate haddock documentation for non library packages...;)

When running "haddock --executables" with a package that has a module which is using a file extension to call a preprocessor, Haddock.getModulePaths will die with:

Setup.lhs: can't find source for module moduleName

If I add a library stanza to the cabal file, the problem is solved.

This issue affects HEAD only.

I must confess I do not understand why this happens, and I'm puzzled. But I don't know the cabal source enough, so I'll leave this to the expert ones.

Cheers, Andrea Rossato

ps: maybe even the short summary could be edited to better describe the problem. An English native speaker could be quite helpful with this...:-)

At least I think I got the problem: preprocessSources will put the preprocessed source in dist/build in case of a library, and in dist/build/exeName/exeName-tmp/ in case of an executable.

But Haddock.haddock will always search dist/build. Hence the call of 'die' in getModulePaths.

Cheers, ar

ps: I must confess I don't get the reason for this difference so my instinct would be to change preprocessSources (this is why I'm not attaching any patch).
