I would prefer to use git's mechanisms for discovering this directory -- using implementation detail like reading the file is going to be fragile

I would prefer not to use parametrized fixtures -- they're really difficult to understand and maintain
what you can actually do here instead is write a separate test which consumes this fixture and the makes a worktree from that and call the original test -- it's going to be a lot easier to follow than this action-at-a-distance

Good call! Initially I thought the parameterized fixtures could be a nice approach to consolidate the variants for all dependent tests, but I can definitely see how they can negatively impact maintainability in the long run.

I meant that you would inline this directly in your test above the call to the other test
no need to make a fixture if only one thing is using it

I don't think this is a realistic test -- I expect these to always run inside a git repo

this is probably my fault -- but can you change this to -> bool

Fixes #638
Right now ongoing merges aren't detected in linked working trees, as it is assumed that
.gitis a directory. However, this is not the case for linked working trees. Working trees instead have a.gitfile, which references the path to the git directory like this:So when we are dealing with a linked working tree, we just have to readjust the git directory to the one referenced in the
.gitfile.
