Describe the issue
Bitwise OR operators which use pipe "|", i.e 1 | 2 get confused with block parenthesis syntax wich are two pipes, i.e.

[1,2,3].each do |num|
   # ...
end

Currently, anything after a pipe is forever highlighted as a parameter until another pipe appears.

Which language seems to have the issue?
ruby

Are you using highlight or highlightAuto?
Either one.

Sample Code to Reproduce

1 | 2 # Bitwise OR
puts "between '2' and '5.times' are all hljs-params"
5.times do |num|
 puts num
end

Expected behavior
Bitwise OR operator "|" should work just like any other &^~+-*/ etc.
