Could you add a comment to both the override and the fetchpatch lines describing why they are needed, linking to any relevant upstream issues/PRs, and adding a guess about when they can be removed (when a new upstream version is released??).
Also, please rebase this onto haskell-updates and change the base branch on Github to haskell-updates.
The hackage-packages.nix change was generated by hackage2nix v2.15.1 from Hackage revision commercialhaskell/all-cabal-hashes@ad4a70d.

@peti I know we normally don't commit these changes to hackage-packages.nix in PRs, but I was thinking that the daily automatic update should just overwrite this, so there won't be any sort of problems with merge conflicts or anything.
If I was wrong about this (and there does end up being problems), please let me know.

Motivation for this change
Make idris work.
(This is distinct from #53406, a previous time a megaparsec update broke idris. That was about megaparsec 6→7. This is about megaparsec 7→8. Upstream project has declared that it plans to stay on megaparsec 7 indefinitely.)
