FRIGN d9fa4b3ae7 Audit mkdir(1)
1) No need for strchr() in mkdirp or a while-loop. Rewrite it in
   a sane and readable way.
2) fix usage according to the manpage.
3) order includes, don't align local variables.
4) argc-style-fix.
5) BUGFIX: Don't try to chmod() *argv when mkdir() / mkdirp() failed.
6) Add newline before return in two places.
