Personally, I don't see this problem in my code, because:
- I never use remote_form_for, since unobtrusive JS works even better
- Usually my forms are in a separate partial (e.g.,
"app/views/articles/_form.html.haml") so there's not much to indent
anyway.
Neither is a reason for you to remove your helper; I just thought I'd
point out my general observation that indenting issues such as this
one do not cause many problems in the context of what I consider to be
programming best-practices.
(Incidentally, your helper makes ERB code much cleaner: if you used it
in ERB, you still wouldn't need icky indentation tricks.)

This is a very common situation:
%div{:class => (color == :blue ? 'blue_div' : 'red_div')}
IMO the one-line syntax is better: it keeps the document structure
perfectly clear. (You can throw in helpers or local variables to
improve the legibility of that one line.)
