If given sort keys are all elided there'll be no output except for the
overhead column - actually the TUI shows a noisy output. In this case
it'd be better to show up the sort keys rather than elide.
Before:
$ perf report -s comm -c perf
(...)
# Overhead
# ........
#
100.00%
After:
$ perf report -s comm -c perf
(...)
# Overhead Command
# ........ .......
#
100.00% perf
