2023 needs to be the last year linux shells let you print 'try using "<command> -h" for more information' and instead everything going forward just, by default, prints -h
and only as a stopgap measure. all of -h should just be listed when I hit tab after a -. even if my completions dir is fucked up to hell and back.
reject int main(int argc, char ** argv) aduance to actual goddamn types
although to be fair reject the command line aduance to the present. exorcise the ghost of the VT-100, nuke xterm from orbit, the GUI was not a mistake stop acting like it, the entire tty/pty subsystem is just ass-backwards compatibility
