Currently it does not indent the following properly:

for_foo do |bar|
something   # <-- indented to col 0
end

The problem is ruby-non-block-do-re
"\\(while\\|until\\|for\\|rescue\\)\\>" matches 'for_'

since '_' is the only valid identifier character that is not an
alphanumeric, let's change the re to:

(defconst ruby-non-block-do-re
  "\\(while\\|until\\|for\\|rescue\\)\\>[^_]")
