Ever since the progress infrastructure was introduced in
96a02f8f6d
(common progress display support, 2007-04-18), display_progress() has
returned an int, telling callers whether it updated the progress bar
or not. However, this is:
- useless, because over the last dozen years there has never been a
single caller that cared about that return value.
- not quite true, because it doesn't print a progress bar when
running in the background, yet it returns 1; see
85cb8906f0
(progress: no progress in background, 2015-04-13).
The related display_throughput() function returned void already upon
its introduction in
cf84d51c43 (add throughput to progress display,
2007-10-30).
Let's make display_progress() return void, too. While doing so
several return statements in display() become unnecessary, remove
them.
