closedString#sub and character sequence \' in replacement string

Description
Hi,
I don't know if this is intentional but substitution of \'
and \`
in the replacement string was rather unexpected for me:
2.2.2 :001 > "this is a test".sub(/this/, "some text \\'")
=> "some text is a test is a test"
I would have expected the following result:
=> "some text \\' is a test"
The documentation says nothing about this, just that back-references can be used (i.e. \\d
or \\k<n>
).
A work-around is escaping the escape character:
2.2.2 :001 > "this is a test".sub(/this/, "some text \\\\'")
=> "some text \\' is a test"
Thanks!

It's a spec, but seems there is no docs about it.
This is a documentation issue.
