I am not sure what you mean. Is that to break "bisect"?
Ahh, you meant "command line is parsed but we do not actually show
guides yet, which is done by later patches in this series". OK.

Ugly.
if (show_all) {
... do not touch anything here ...
... but remove "return 0;" ...
}
if (show_guides) {
... show guides but do not "return 0" ...
}
if (show_all || show_guides) {
... we were asked to do either/or --all/--guides ...
... and have done what we were asked to do ...
return 0;
}
This is a tangent, but before all of the above, cmd_help() should
verify that it got no arguments (when show_all/show_guides is in
effect) or it got one argument (otherwise), I think.
