Merge branch 'sg/overlong-progress-fix'

Updating the display with progress message has been cleaned up to
deal better with overlong messages.

* sg/overlong-progress-fix:
progress: break too long progress bar lines
progress: clear previous progress update dynamically
progress: assemble percentage and counters in a strbuf before printing
progress: make display_progress() return void
