So that we can get it working for TUI, where using just pr_err() would
end up making the message emitted to stderr to be erased by the TUI exit
routine restoring the terminal to its previous state.
Now we can see that trying to use a tracepoint field as one of the
--field entries isn't working:
# perf top --stdio --no-children -e syscalls:sys_enter_write --fields
pid,sym,count
Error:
Unknown --fields key: `count'
Usage: perf top [<options>]
--fields <key[,keys...]>
output field(s): overhead, period, sample plus all of
sort keys
