Ruby uses the Oniguruma/Onigmo regular expression engine, including the underlying
character encoding framework. In contrast to other code implementing Ruby, the
regular expression engine related code is formatted with two spaces per indent
level. This commit adds rules for these files. (The commit may not completely cover
all related files.) [ci skip]
