[issue14366] Supporting bzip2 and lzma compression in zip files

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

ISTM that the LZMA support differs from the specification, see

http://www.pkware.com/documents/casestudies/APPNOTE.TXT

In particular, there appears to be no support for the EOS marker, which should be emitted when compressing.

Changing the LZMA module is fine as long as it
a) happens before the release of 3.3, and
b) is truly justified by the ZIP spec

I also recommend to split this issue into two: bzip support and lzma support. Adding bzip support might be easier.
