What are the steps to reproduce this issue?

1. Make indented doc comment, like this:

   do
   	--- This is a
   	--- multiline
   	--- doc comment.
   	local x = 5
   end

2. Format using whatever keybind (i.e. Cmd+Option+L)

3. it gets changed to use spaces instead

   do
   	--- This is a
       --- multiline
       --- doc comment.
   	local x = 5
   end

   (yes, this is exactly what happens, the first line being indented correctly and the subsequent lines being forced to use spaces)

What happens?

see above

What were you expecting to happen?

I would expect the indentation to use tabs if I have it configured to do so

Any logs, error output, etc?

Nope

Any other comments?
