Comment (by sjakobi):

 `--show-iface` reveals that e.g. `GHC/Show.hi` ''does'' contain docs for
 `show`:


 {{{
   show:
     " A specialised variant of 'showsPrec', using precedence context
  zero, and returning an ordinary 'String'."

 }}}

 So either we're loading the wrong iface our `Name` isn't the same as the
 one in the `DeclDocMap`.
