svn commit: r289080 - head/usr.bin/truss

[Bryan Drewery]

Author: bdrewery

New Revision: 289080
URL: https://svnweb.freebsd.org/changeset/base/289080

Log:
  Let -c imply -S (hide signal output).
  
  Without this, the signals are shown seemingly randomly in the output before
  the final summary is shown.  This is especially noticeable when there is
  not much output from the application being traced.
