This patch is a workaround for a "tail" that should, but doesn't, act like
GNU tail, in that it only reads from one file, even if multiple files are
given on the commandline:

    15273738 tail should behave like head (multiple files)

Since we should fix Solaris tail, this patch is highly Solaris-specific,
and should not be passed upstream.
