For `tab-always-indent' t it might make sense to do `beginning-of-line'
before the `forward-sexp'.  Otherwise it should work wherever
`forward-sexp' behaves reasonably.  BTW, isn't

   ((memq indent-line-function '(indent-relative indent-relative-maybe))
    (funcall indent-line-function))
   ;; Indent the line.
   (t
    (indent-according-to-mode))

semantically equivalent to

   (t
    (funcall indent-line-function))
