Pekka Enberg 99ff715054 perf trace: Simplify '--summary' output
The output of 'perf trace --summary' tries to be too cute with
formatting and makes it very hard to read.  Simplify it in the spirit of
"strace -c":

[penberg@localhost libtrading]$ perf trace -a --duration 10000 --summary -- sleep 1
^C
