	As for the deprecation of lost-found, I think it is correct, and 
	should not be reverted.  We _do_ have way too many commands, and 
	lost-found logically _belongs_ into fsck.  The proper fix is to 
	fix fsck --lost-found.

	Now, I did not yet look closely at the output of 
	git-lost-found.sh, as I already switched to "master" in the hope 
	that 1.5.5-rc2 will be almost identical to 1.5.5, and I fully 
	intend to push for a quick release (after the pending "fetch" 
	resolutions).

	After 1.5.5, I will tend to lost-found.
