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.
