To improve perf config usability, we should probably also recognize underscores in perf config entries, i.e. the following variants should both work: as suggested by Ingo Molnar
print_percent = 1 print-percent = 1 So, add functionality for it. 'annotate' section has variables that contain '_' underscores like: hide_src_code use_offset jump_arrows show_nr_jumps However other sections has variables that contain a '-' dash or neither it or underscore i.e. ui.show-headers call-graph.print-limit tui.report So, convert the characters if typing errors about underscores or a dash when parsing the config file.
