Haddock generates Source links to re-exported items without module names (under Nix; possibly in general)

[lf-]

I noticed this in Esqueleto although it is probably reproducible in packages with fewer dependencies.

Reproduction:

$ nix-build '<nixpkgs>' -A haskellPackages.esqueleto.doc
/nix/store/9mh0h5ll38wxwan66r79n7ysfvfsw16v-esqueleto-3.5.5.0-doc
$ firefox result-doc/share/doc/esqueleto-3.5.5.0/html/Database-Esqueleto.html#t:PersistField

Then click the Source link next to PersistField, which has an href property of file:///nix/store/d121c0wdrwsnms2m9s48fbw7104rqmbz-persistent-2.13.3.5-doc/share/doc/persistent-2.13.3.5/html/src, missing a file name. This is significantly more troublesome on Hoogle which doesn't show directory contents.

This is likely a related shape of bug as was fixed in #1482 but it's on the module pages rather than in the hyperlinker itself.

I imagine that this is fixed by #1482. Please do re-open if it is not.

I believe it was not; I can try reproducing again but I remember filing this after having applied that patch.

(fyi i can't reopen myself for some reason)

Great, thank you
