Merge branch 'refs/heads/t/short-log'

A few patches which change dss_log() to only print the time stamp
and the function if dss is executing the "run" subcommand.

Cooking for a week.

* refs/heads/t/short-log:

  Save the subcommand pointer in a global variable.
  main(): Don't initialize user data pointer.
