Here are two patches for this, plus one to use EXIT_AM_SKIP more.

Subject: [PATCH] tests: Fix compressed test output padding logic

The current logic tries to count from 1 to 40 and ignores paddings
of 0 and 1 to 40. This doesn't work for counter + 1 mod 40 == 0 like
here for counter value 159

TEST: virsh-all
      ........................................ 40
      ........................................ 80
      ........................................ 120
      ....................................... 159 OK
PASS: virsh-all

Instead count from 0 to 39 to fix this.
