[erlang-questions] Stripping slashes from a string

[Martin Dimitrov]

With 6 it produces double backslashes making the result equivalent to
the initial text:

(dilbert@REDACTED)17> re:replace("\\r \\n text", "\\\\(r|n)",
"\\\\\\1", [{return,list}, global, unicode]).
"\\r \\n text"
(dilbert@REDACTED)18>

Best regards,

Martin
