PATCH: better progress reporting

[Cameron Simpson]

I've been looking at the --progress reporting, which is somewhat
improved these days.  But look at this output of this evening rawhide
mirror update:

	[...]
	perl-DB_File-1.75-27.i386.rpm
	       73430 100%  519.63kB/s    0:00:00
	perl-DB_File-1.75-28.99.3.i386.rpm
	       61783 100%  533.94kB/s    0:00:00
	[...]

Now, while it's good to have the ETA ticking down as something is fetched,
it's irritating to have this history there on the screen afterwards with
those unhelpful zeroes.

Thus the appended patch to util.c in the current CVS head, which for the
final progress report, puts to elapsed time for that file in the report
instead of the time remaining.

Applied (clean) to 2.5.4, it says this:

	++ /home/cameron/tmp/rsy/rsync-2.5.4/rsync -rlHt -z -v -P --delete --include-from=.mirror-rsync '--exclude=xemacs*' '--exclude=kernel-source*' '--exclude=postgresql*' mirror.aarnet.edu.au::redhat/rawhide/i386/RedHat/RPMS/. ./redhat/rawhide/i386/RedHat/RPMS/.

	tk-8.3.3-67.i386.rpm
	     1371196 100%  433.77kB/s    0:00:03

Martin, can this go in for 2.5.5 please?
Any nay sayers?
