+ * progmodes/ruby-mode.el (ruby-smie--implicit-semi-p): Check for
+ `:' before binary operators (bug#16609). Don't check for `:'
+ before `[' and `(', or their syntax status. A percent literal
+ can't end with either.
+ (ruby-font-lock-keywords): For built-ins that require arguments,
+ check that they're followed by something that looks like argument
+ (bug#16610).
