a '*' entry in blackbox.track is interpreted as log everything

  $ hg --config blackbox.track='*' \

(only look for entries with specific logged sources, otherwise this test is
pretty brittle)

With chg, blackbox should not create the log file if the repo is gone

  $ hg init repo1
  $ hg --config extensions.a=! -R repo1 log
  $ rm -rf $TESTTMP/repo1
  $ hg --config extensions.a=! init repo1

#endif

blackbox should work if repo.ui.log is not called (issue5518)
