* lisp/progmodes/ruby-mode.el (ruby-smie--implicit-semi-p):
No implicit semi after "^", "and" or "or".
(ruby-smie-grammar): New tokens: "and" and "or".
(ruby-smie--args-separator-p): Fix the check for tokens at POS.
Exclude "and" and "or".  Remove "do" in order to work around token
priorities.
(ruby-smie-rules): Add all infix tokens.  Handle the case of
beginning-of-buffer.
