1) Any path passed to mkdir -p beginning with '/' failed, because
it would cut out the first '/' immediately, passing "" to mkdir.
2) Running mkdir -p with a path/to/dir without trailing '/' would
not create the directory.
This is due to a wrong flag-check I added in the main-loop.
It should now work as expected.
3) With the p-flag given, don't report an error in case the last
dir also exists.
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.
It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).
This is also more consistent with the other suckless projects
around which don't use boolean types.
