    Fix search dirs used for pre-processing executables · d28e1b90

    It was combining the executable's hs-source-dirs with the library's
    hs-source-dirs when pre-processing executables. This was inconsistent
    with the search path used for finding ordinary .hs files and with
    sdist and lead to confusing behaviour. See ticket #161.
    If an executable needs source files from the library then it must specify
    the right hs-source-dirs, including '.' if appropriate.
    The behaviour is that if hs-source-dirs is not specified then the default
    is '.' however if hs-source-dirs is specified then '.' is not implicitly
    added. If it's needed then it must be added explicitly. This was always
    the case for ordinary .hs files, this patch just brings things into line
    for files that need pre-processing.
