Re: update-index --index-info producing spurious submodule commits

"ls-tree -r HEAD foo" is probably what you meant to say.

Thanks very much for the clue - that works.  The update-index
documentation should probably say that only blobs (or perhaps commits
intended to be submodules??) are acceptable, and perhaps say "ls-tree
-r" instead of ls-tree.

Makes sense.  Please make it so.

By the way, for this particular application I wonder if something like

	git ls-files -z <dir> | git update-index -z --force-remove --stdin
	git read-tree --prefix=<dir>/ <tree>

would be easier.  Or a commit-filter. :)

	tree=$1
	shift
	tree=$(
		git ls-tree -z "$tree" |
		perl -0ne '
			chop;
			my ($info, $name) = split(/\t/, $_, 2);
			if ($name eq "<dir>") {
				printf("040000 tree <good tree>\t<dir>\0");
			} else {
				printf("%s\0", $_);
			}
		' |
		git mktree -z
	)
	git commit-tree "$tree" "$@"

Thanks,
Jonathan
