Subject: Epilogue area in MIME multipart_related docs is not ignored

Hello,

When PUTting a document with attachments in MIME multipart/related =
format, CouchDB (1.2.0 on Mac OS X) throws a badmatch error in =
doc_from_multi_part_stream() if any bytes are following the final =
boundary.

For example, if the last body part ends with

\r\n=3D=3D1234=3D=3D\r\nabc

the error reads

[error] [emulator] Error in process <0.18266.with exit value: =
{{badmatch,{<<7 bytes>>, =
#Fun<couch_httpd_db.23.117176975>,ok}},[{couch_doc,'-doc_from_multi_part_s=
tream/2-fun-1-',3,[{file,"/Users/hs/prj/build-couchdb/dependencies/couchdb=
/src/couchdb/couch_doc.erl"},{line,512}]}]}

where <<7 bytes>> is 2 + the number of bytes following the two ending =
hyphens (5 in this example). Everything works fine if the last body part =
ends with two hyphens only (i.e. the epilogue is left blank).

However, according to RFC 1521 Sec. 7.2.1 =
(<http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html>), =
"implementations should ignore anything that appears before the first =
boundary or after the last one".

Regards,
