Pcut results reporting sets of mental alarms

[Jiri Svoboda]

Pcut reports the results of each test suite as (N of M failed). The sole appearance of the word 'failed' sets of mental alarms when one is quickly glancing through the results trying to look for failure.

If nothing failed there should be no words like failed or error.

E.g.:
all pass

or

N of M pass
N of M pass, Y failed (when Y > 0)

or

total: N, passed: M
total: N, passed: M, failed: Y (when Y > 0)
