I did not think about it to be so fresh, I already got used to it as is it
being pushed for the rpm packaging in Fedora.

The file format of current xz-4.999.9beta is already guaranteed to be the one
used in final expectde xz-5.0, specified at:

`lzma' is decompressed by `xz' the same way `compress' is decompressed by
`gzip'.  `lzma' was AFAIK already used as the internal format of SuSE rpm so
it already became a format requiring backward compatibility.


I see the xz proposal did not find enough acceptance by GDB maintainers, OK, np.
