Description
Fixed in #55

Changed in version 3.12: Unrecognized escape sequences produce a SyntaxWarning.
In a future Python version, they will raise a SyntaxError.

This appears to be covered by the existing PR #55: it changes the two ASCII art string literals and the parse_multi_value_header() regex referenced in this issue.
