Indentation detection

[BNAndras]

At the moment, the test runner relies on tabs and not spaces being used in exercise files. @ErikSchierboom, does the web editor insert tabs or spaces when the tab key is pressed?

Isaac's suggestion was to use sed to convert multiple spaces back to tabs.

That sounds like a good idea.

Just tested the web editor on https://exercism.org/tracks/gdscript/exercises/hello-world/edit with 0, 1, 4, 5, 8, and 9 spaces before the return, and it worked in all cases except 0.

Same is true with the local test runner.

I guess this can be closed, if there are no objections / I'm not missing anything.
