Avoid line breaks due to line length in Hoogle (#868)
* Avoid line breaks due to line length in Hoogle
Hoogle operates in a line-oriented fashion, so we should avoid ever
breaking due to long lines.
One way of doing this non-intrusively is to modify the 'DynFlags' that
are threaded through the 'Hoogle' module (note this is anyways only
passed through for use in the various 'showSDoc' functions).
* Amend test case
(cherry picked from commit 657b1b3d519545f8d4ca048c06210d6cbf0f0da0)
