[gentoo-pms] [PATCH] unpack: Fix list of suffixes for tar.gz, tar.bz2, and lha files.

[Ulrich Mueller]

I've noticed two mistakes in the suffix list for unpack:
  - *.tbz is listed under gzip-compressed tar files, but belongs under
    bzip2-compressed tar files
  - *.lhz should be *.lzh (both Portage and Paludis say so)

The patch included below fixes this. I've also rearranged some lines,
so that all gzip and bzip2 compressed files are grouped together.

However, with gzip there's another inconsistency:
  - *.gz *.Z *.z for gzip
  - *.tar.gz *.tgz *.tar.Z for gzip-compressed tar (i.e., no *.tar.z)
I wonder what was the intention here. *.Z was the old Unix compress
(which can be unpacked by gzip though). *.z was used by the very first
gzip versions, but that was 20 years ago. And in fact, there's no *.z
file on our distfile mirrors.

As the spec doesn't mention *.tar.z, maybe we should drop *.z too?
