>Description:
	"etcupdate -a" stores checksums in subdirectories of /var/etcupdate,
	specifically dev, etc, root, and var.  When it is used together with
	the "-d destdir" option, the checksums of unchanged files are written
	in subdirectories with those same names under /var/etcupdate/<destdir>,
	rather than /var/etcupdate.
>How-To-Repeat:
	etcupdate -a -l -d otherroot -s etcsrcdir

	or read the code in the first conditional block of the
	diff_and_merge_file() function.  It's obviously inconsistent with
	the intended meaning of the install_checksum() function (as documented
	with its definition) and with all other invocations of that function.

	Issuing the command leads to numerous error messages about missing
	directories, and many of the checksums then show up under
	/var/etcupdate/otherroot.
>Fix:
	This patch fixes the problem.  I checked the rest of the script
	and didn't find any other mistakes like this.
