perf tools: Return all events as auto-completions after comma
It's a follow up for one previous patch "perf tool: Improve bash command
line auto-complete for multiple events with comma."
It fixes an issue that no events are displayed when <TAB> is directly
typed after comma.
With this patch, now the result is:
root@skl:/tmp# perf stat -e cpu-cycles,<TAB>
Display all 2389 possibilities? (y or n)

One remaining issue is that the auto-completions doesn't work well
for the event with ':'. For example, clk:clk_enable.
Because ':' is set as WORDBREAK by default in bash. Need more work
for this case.
