Done. Test, please.

Multi-part archives should always be identified as such.  As with
single-part binaries, they should also be identified as yEncoded until
yEncoding becomes more mainstream.

The (strongly) recommended format for subject lines for multi-part binaries
is:

[Comment1] "filename" yEnc (partnum/numparts) [size] [Comment2]

You could send me such samples you mentioned.
