The interface was meant to be that the argument names a tarball, not a
directory.  This allows the version number to be extracted from the
tarball name.  For example, snapshots are in directories with names such
as "2002-02-18", with no "gcc-" prefix, and the tarballs in them have
names such as "gcc-20020218.tar.gz".  The usage message still says "[-p
previous-tarball]", rather than anything referring to a directory.  I
don't think this will work with the change you made - you'll need to
finish the change so that snapshots get both parts (the old version in the
tarball names, and the directory) correctly.

Please do make the appropriate fixes, in time for the next snapshot.
