bug#919: distributions in lzma or bz2?

[Karl Berry]

emacs-22.3.tar.gz is       39587396 bytes.
Compressed with lzma, it's 26752360 bytes.
(I didn't check bzip2, presumably it's somewhere in between.)

That could be a lot of download bandwidth saved.  How about making it
available both ways, at least for next time?  (= install lzma-utils from
http://tukaani.org/lzma/download and add dist-lzma to the automake
options.)

Best,
karl
