With earlier elm versions, a separate package file is maintained for
tests, which when properly configured enabled the compiler to find what
it needed to compile the tests. Under elm 0.19, test dependencies are
managed in the top-level package file, so `elm make` will fail on the
tests. `elm-test make` is required in this case.

Looks like elm-make only respects /dev/null, even on Windows. The person
who wrote this linter maybe did not test it on Windows, and wrote the
code in the way you would expect to be solid by using NUL on Windows.
However it seems elm-make is not actually making use of /dev/null but
rather using it as a form of flag. Ironically this seems to be what is
already described in the comments; I added some clarification.
* Improve elm linter
Some types of errors do not return nice JSON.
Show them on the first line instead of showing nothing.
* Remove unnecessary properties from elm linter
* Add a vader test for elm-make linter
* Test non-JSON elm-make errors are shown
* Filters out unrelated errors in Elm linter
The function now filters out errors that are unrelated to the file,
those that were found in imported modules.
It does this by comparing the temp directory environment variable to the
file name in the elm output. If the file begins with the temp directory,
then it sould be included (it's from the buffer).
* Changing output to '/dev/null'
Turns out the compiler only accepts /dev/null as an ignorable name. It's
hard-coded here
https://github.com/elm-lang/elm-make/blob/master/src/Flags.hs
Changing this allows Windows linting to work. Otherwise the compiler
errors when using "nul"
* Fixes for Windows
Should now be able to successfully handle Windows.
Windows seemed to not handle the ";" properly, so I switched it to "&&",
which probably should've been done anyway to prevent false positives.
Oddly, matchend(l:error.file, l:temp_dir), and various other regex
solutions, couldn't properly match the two. Subsetting did though, hence
the new solution.
* Applying corrections
Made the file check case-insensitive for Windows, case-sensitive for
Unix/non-windows.
Added comment explaining hard coding of 'dev/null'
* Spelling correction
* Minor corrections
Actually uses the is_file_buffer variable now, added space between the
if statements, and added space between '-'
* Add support for Elm linting
* Adding documentation for Elm
* Adjusting spacing
* Addressing concerns listed in pull request
Removed the s:FindRootDirectory function as it does not make much sense
in this context. Adjusted the rest of the code to handle the removal of
that function, including using the ale#util function to find the nearest
file.
Ensured that when an empty filepath is found, the code does not attempt
to change directories.
Ensured that the linter would take from stdin using the wrapper.
