I wrote a major mode [1] some times back (with a little
help from my friends, as always) and I remember I
wanted to have indentation just like in C because the
syntax was sort of, but not quite, as C.

So I wrote the following defun - perhaps it can be of
value to you:

(defun fpscalc-indent-line ()
  "Indentation function."
  (if (bobp) (indent-line-to 0)
    (let ((not-indented t)
          (cur-indent   0)
          (indent-unit  2))
      (if (looking-at "^[ \t]*}")
              (forward-line -1)
              (setq cur-indent (- (current-indentation) indent-unit) ))
            (if (< cur-indent 0) (setq cur-indent 0)) )
          (while not-indented
            (forward-line -1)
            (if (looking-at "^[ \t]*}")
                  (setq cur-indent (current-indentation))
                  (setq not-indented nil) )
              (if (looking-at "^[ 
                    (setq cur-indent (+ (current-indentation) indent-unit))
                    (setq not-indented nil) )
                (if (bobp) (setq not-indented nil) ))))))
      (indent-line-to cur-indent) )))

Then somewhere:

(setq indent-line-function 'fpscalc-indent-line)
