No. My editor produces the ASCII code for horizontal tab, when I hit the tab key. Just as it produces the ASCII code for a when I hit the a key.
That's how it should be.
Not true: most editors don't insert a ^H when you hit the backspace key, so why should they insert ^I when you hit the tab key? This whole problem boils down to one thing: people configure their editors to display tab stops at something other than every 8 columns. There's no reason not to use 8 column tab stops, so please don't do it. Not only will your code be unreadable by someone using standard tab-stop settings, but it will be interpreted differently by a Haskell compiler. Tab characters are a primitive compression mechanism, nothing more. No-one is saying that you can't use units of 4 columns for indentation, just that you can't use tab characters for that.
