I usually encounter this when there has once been a branch called
"wip/rae" (so .git would have a *file* wip/rae), but now there's a
branch called "wip/rae/remove-tc-dep", so "wip/rae" should be a
directory, but it's already in .git as a file! I think "git remote
prune" fixes this, but I can't entirely recall.

Aieee! All my GHC repos are failing with this. As a result I can’t pull. What should I do? Thanks!
