git describe fails without tags

Hello,

using git describe on Linus' sparse repo results in:

	uzeisberger@io:~/gsrc/sparse$ git describe
	fatal: cannot describe '62ac6c16058aba8693fd5827379debc5f57b60f5'

The reason is, that there exist no tags at all, so right, there is no "most recent tag that is reachable from HEAD".

I wonder if it would be sane to assume an implicit tag for the empty repository, s.t. git describe results in

	<empty>-62ac6c16

(whatever name is choosen for <empty>).

Any opinions?

Best regards Uwe
