Let's say tab-width is 8 and elisp-mode uses tabs for indentation. In
the following snippet, arg2 should be indented with a tab.

#+BEGIN_SRC emacs-lisp
(some-f arg1
         arg2) ;; arg2 is indented at column 8
#+END_SRC

If I add two spaces at the beginning of the block. It should visually
look like this:

#+BEGIN_SRC emacs-lisp
   (some-f arg1
         arg2) ;; arg2 is indented at column 8
#+END_SRC

Calling =indent-to= would rather put the two spaces after the tab
character. But then we lose this idea of clean separation between the
org indentation and the native indentation, and we will need to
convert the indent of every line on subsequent edits (org -> elisp),
as well as for tangling, or code execution. If we have to do this, we
might as well just respect the org buffer =indent-tabs-mode=, and redo
every indentation with each conversion. This could possibly be costly
when tangling a large buffer.

The visual breakage would be much more common than those more serious
issues, which had gone unnoticed so far.
