Hello,

I had some old csh auto-indentation code from https://github.com/Tux/tcsh/blob/tux/csh-mode.el that worked pretty well but relied on the code that got removed in https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=f9504ffba2e2604338c243dd77c877bbb8162e4a

I had this code that relied on the now-removed code: https://github.com/kaushalmodi/.emacs.d/blob/fec110f5281e0bd4fe5c16ca18832e1df1c8f27f/setup-files/setup-shell.el#L43-L148

Can you please add SMIE auto-indentation support for csh/tcsh shell scripts?
