trace: tighten up trace-events regex to fix bad parse
Use \w for properties and trace event names since they are both drawn
from [a-zA-Z0-9_] character sets.
The .* for matching properties was too aggressive and caused the
following failure with foo(int rc) "(this is a test)":
Traceback (most recent call last):
