There is a slight misalignment in -A -I output.
For example,
perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000
# time CPU counts unit events 1.000440863 CPU0 1,068,388 cpu/event=cpu-cycles/ 1.000440863 CPU1 875,954 cpu/event=cpu-cycles/ 1.000440863 CPU2 3,072,538 cpu/event=cpu-cycles/ 1.000440863 CPU3 4,026,870 cpu/event=cpu-cycles/ 1.000440863 CPU4 5,919,630 cpu/event=cpu-cycles/ 1.000440863 CPU5 2,714,260 cpu/event=cpu-cycles/ 1.000440863 CPU6 2,219,240 cpu/event=cpu-cycles/ 1.000440863 CPU7 1,299,232 cpu/event=cpu-cycles/
The value of counts is not aligned with the column "counts" and the event name is not aligned with the column "events".
With this patch, the output is,
perf stat -e cpu/event=cpu-cycles/ -a -A -I 1000
# time CPU counts unit events 1.000423009 CPU0 997,421 cpu/event=cpu-cycles/ 1.000423009 CPU1 1,422,042 cpu/event=cpu-cycles/ 1.000423009 CPU2 484,651 cpu/event=cpu-cycles/ 1.000423009 CPU3 525,791 cpu/event=cpu-cycles/ 1.000423009 CPU4 1,370,100 cpu/event=cpu-cycles/ 1.000423009 CPU5 442,072 cpu/event=cpu-cycles/ 1.000423009 CPU6 205,643 cpu/event=cpu-cycles/ 1.000423009 CPU7 1,302,250 cpu/event=cpu-cycles/
Now output is aligned.
