For compatibility @command{tail} also supports an obsolete usage
@samp{tail -@var{count}[bcl][f] [@var{file}]}, which is recognized
only if it does not conflict with the usage described
-above. @var{count} is an optional decimal number optionally
+above. This obsolete form uses exactly one option and at most one
+file. In the option, @var{count} is an optional decimal number optionally
followed by a size letter (@samp{b}, @samp{c}, @samp{l}) to mean count
by 512-byte blocks, bytes, or lines, optionally followed by @samp{f}
which has the same meaning as @option{-f}.
