ute hash with 'file-hash*' instead of
'port-hash' from (gcrypt hash) module. This allows us to compute
hashes for directories.
* doc/guix.texi (Invoking guix-download): Add @item entries for
`git', `commit', `branch' and `recursive' options. Add a paragraph in
the introduction.
* tests/guix-download.sh: New tests. Move variables and trap definition
to the top of the file.
