#15 MIME delimiter spanning multiple lines does not work

[Anonymous]

RFC2231 apparently allows a value to span multiple lines using the *n notation. Sharp does not appear to join these together and as a result the contained message is not split properly.

Example:

Content-Type: multipart/alternative;
boundary*0=----0000000000000000000000000000000000000000000000000000000000;
boundary*1=00000

Expected: A multipart message with its respective message split into separate MIME part objects.

Actual: Not a multipart message and raw MIME data in text body.

Rough example attached.
