ruby-mode misses a regexp just after an open brace ('{') or a vertical
bar ('|'). As the result, `forward-sexp` and regexp highlighting do not
work expectedly (or as a ruby interpreter interprets).
ex.
tap { /'/ }
This "/'/" should be parsed as an regexp matches a single quote, but the
first operator is parsed as a division operator and the succeeding
single quote is parsed as a beginning of a string.
Same for `{|x| /'/}`.
