Please, could it be possible to stop spreading the false idea that xz is 
somehow the only succesor to lzma(_alone)? They came from different 
authors (Ville Koskinen, Lasse Collin) and do not share a single line of 
code.

$ lzma -h

lzma 4.32.7 Copyright (C) 2005 Ville Koskinen

$ xz -h

(As you can see, xz does not even display a proper copyright notice).

Given that lzip "supersedes"[1] lzma in the creation of compressed 
tarballs as much as xz does, I propose to replace this:

+  - The `lzma' compression format for distribution archives has been
+    deprecated in favor of `xz', and will be removed the next major
+    Automake release (1.12).

with this:

+  - The `lzma' compression format for distribution archives has been
+    deprecated, and will be removed in the next major Automake release
+    (1.12).


[1] There is a program in the lzip family able to decompress lzma_alone 
files; pdlzip. http://www.nongnu.org/lzip/pdlzip.html
