SF bug #1582282; decode_header() incorrectly splits not-conformant RFC
2047-like headers where there is no whitespace between encoded words. This
fix changes the matching regexp to include a trailing lookahead assertion that
the closing ?= must be followed by whitespace, newline, or end-of-string.
This also changes the regexp to add the MULTILINE flag.
