+
+	* progress.c: Renamed dp_* functions to dot_* for greater clarity
+	and consistency with bar_*.
+	(print_download_speed): Get rid of the unneeded '@' character.
+	(create_image): Fix download rate geometry.
+
+	* progress.c (print_elapsed): Remove spurious space.
+	(print_elapsed): Renamed to print_download_speed, since that's
+	what it does.

 	* progress.c (bar_update): If the downloaded amount becomes larger
