[issue44134] lzma: stream padding in xz files

[rogdham]

rogdham <contact at rogdham.net> added the comment:

It must be decided what to do in the following cases, which are not valid per the XZ file specification, but supported by the lzma module (and tested):
 1. different format concatenated together (e.g. a .xz and a .lzma); this somehow includes tailing null bytes (12 null bytes is a valid .lzma)
 2. trailing junk (i.e. non-null bytes after the stream)

The answer may be different depending on the format arg (e.g. FORMAT_AUTO vs FORMAT_XZ).
