Use FindNearestFileOrDirectory, perl languageserver

[rymdbar]

Update to use mentioned function to find both .git/ directories and .git work-tree files.

[rymdbar]

Tests are failing due to supposedly:

./ale_linters/perl/languageserver.vim:20 Blank line required after let

However, there is a blank line after let (or rather before if). The documentation does not appear to mention anything about any non-existing required empty line under these circumstances, nor does vint indicate it. Is the test-suite misidentifying this as a false positive? is the documentation incomplete? or am I reading something incorrectly?

@rymdbar this error is from the ale_custom_linting_rules linter. I recommend you enable it in your configuration so vim/nvim warns you about these issues:

linters = {
   vim = { "vint", "ale_custom_linting_rules" },
}

The error is misleading since it says "after" but I can get the warning to dissapear by adding a blank line before that line.

Yes? As already covered in previous comment.

So you're suggestion, @hsanson, is that we unblock this PR by updating the documentation? Please feel free to suggest how the new wording should be.

I'm more getting the hunch this is caused by a false positive. If it indeed is correct, what is the motivation for requiring an empty line at this position?
