Should it?
The use case that I have in mind is this:
. directory DIR exists on disk, and has files in it
. the archive includes directory DIR with files in it, not
necessarily identical to those on disk: some files on disk don't
exist in the archive, and vice versa
When I unpack such an archive outside Emacs, what happens (and what
I'd expect to happen) is the following:
. files in DIR on disk that don't exist in the archive are unaltered
. files in DIR in the archive that don't exist on disk are unpacked
into DIR on disk
. non-directory files in DIR that exist both on disk and in the
archive are overwritten with the version in the archive
. sub-directories in DIR that exist both on disk and in the archive
are NOT being overwritten; instead, they are recursively handled
as described above, i.e. missing files are added and common files
are overwritten
. as a corollary from the last item, an empty sub-directory of DIR
in the archive that also exists on disk will NOT be emptied on
disk, but will be left intact with the files it had before
unpacking
Will the unpacking you propose behave in the same way? If not, we
need to augment it so it does.
In particular, unpacking into an existing directory should "just
work", it makes little sense to me to fail in that case, as that isn't
what Tar and similar utilities do, at least IME. We may decide asking
the user for confirmation in that case, but given the confirmation
should proceed as above.
