Are you just copy-pasting this same "fix" across a bunch of different repos? You didn't even check if CI passes.

[phanen]

Yeah, I first did this in fzf-lua. But I think this is caused by my custom conform formatter (which replace vim.fn to fn for me...

@phanen this might need to be rebased on master for the tests to pass. They don't look like they are coming from the specific changes you made.

[phanen]

Sorry. Clearly I haven't developed a good habit yet. I rebase in conform.nvim but forget about this one...

Looks good, thanks!
