[pve-devel] [PATCH installer v2 5/6] auto: avoid printing unnecessary progress update lines

[Christoph Heiss]

In case the progress message did not contain any text and the percentage
did not change, don't print another (useless) line.

Changes v1 -> v2:
  * if the percentage was updated w/o any text, reuse the last message
