commit 2c87ff9a6ad551af149358c28e13cd5058c48043

    pmlogger_*: add shell escape for "directory" field of control file
    
    The control file used by pmlogger_check and pmlogger_daily now
    supports embedded shell escapes for the "directory" field.
    
    From the man page ...
    The allowed constructs are:
        Â Any text (including white space) enclosed with $( and ).
        Â Any text (including white space) enclosed with ` and ` (back quotes).
        Â Any text (including white space) enclosed with " and " (double 
quotes).
        Â Any word containing a $ (assumed to introduce an environment
          variable name).

    qa/993&1094: (new) exercise shell escape in pmlogger control file
    
    Recent pmlogger_* changes to allow the directory field of the
    control file to contain embedded sh(1) constructs.

    qa/184&292: ensure primary pmlogger is restarted
    
    These tests kill off the primary pmlogger and did not restart
    it.  When running _all_ of QA the issue is masked because some
    test later on restarts the primary pmlogger, but running
    -g logutil exposed the problem.

    qa/089: improve test stability
    
    After recent "log early" changes to pmlogger, the archive used in
    this test (qa/src/bar) that is created on the fly as needed may
    contain some variablility in the timestamp intervals at the
    beginning of the archive.  Skip this first few samples to get
    into the stable part of the archive.
