--- Begin Message --- Subject: [PATCH core-updates 1/1] guix: packages: Allow patch-and-repack to work with plain files. Date: Sun, 10 Jan 2021 15:05:35 -0500
This change allows the use of the snippet field on a single file origin.
Previously, the patch-and-repack procedure would fail on plain files, as it
would end up invoking tar when attempting to extract non-tarballs.

* guix/packages.scm (patch-and-repack): Only add the compressor utility to the
PATH when the file is compressed.  Bind more inputs in the mlet, and use them
for decompressing single files.  Adjust decompression and compression routines.
[decompression-type]: Return #f when no known compression extension is used.
[tarball?]: New nested procedure.
* tests/packages.scm: Add tests.  Add missing copyright year for Jan.

I've been building a sizable part of core-updates on top of this change
now for nearly two weeks, and in this time it's already come handy
twice.

I've made sure the tests ran fine and pushed to core-updates as commit
cfcead2e515c0dae02127e5a76496463898be6b6.

Let me know if anything breaks :-).
