The default output from "fsck" is often overwhelmed by informational message on dangling objects, especially if you do not repack often, and a real error can easily be buried. Add "--no-dangling" option to omit them, and update the user manual to demonstrate its use. Based on a patch by Clemens Buchacher, but reverted the part to change the default to --no-dangling, which is unsuitable for the first patch. The usual three-step procedure to break the backward compatibility over time needs to happen on top of this, if we were to go in that direction. Signed-off-by: Junio C Hamano <gitster@pobox.com>
