[bug#73795] [PATCH] Add support for the bzip3 compression tool to automake.

[Karl Berry]

    Sorry. That was a mistake. bzip3 does not read the BZIP2 environment
    variable.

Ok, will adjust, no problem.

Does bzip3 read any envvar? I guess there are no "levels" of compression
with bzip3 (?), but it could still be useful ... --thanks, karl.
