`tabs_in_doc_comments` suggests me to use spaces for indentation

Lint name: tabs_in_doc_comments

I tried this code:

	/**
	 * Some code documentation
	 * string.
	 */

I expected to see this happen: The lint only activates when using tabs within the comment block, and not to indent the block.

Instead, this happened: I get a lint suggesting to replace my tabs with spaces. Doing this would result in mixed indentation (I generally use tabs and the lines with the comment would use spaces instead), which is bad.
