Previously, with -p, the specified directory and all of its parents
would be 0777&~filemask (regardless of the -m flag). POSIX says parent
directories must created as (0300|~filemask)&0777, and of course if -m
is set, the specified directory should be created with those
Additionally, POSIX says that for symbolic_mode strings, + and - should
be interpretted relative to a default mode of 0777 (not 0).
Without -p, previously the directory would be created first with
0777&~filemask (before a chmod), but POSIX says that the directory shall
at no point in time have permissions less restrictive than the -m mode
Rather than dealing with mkdir removing the filemask bits by calling
chmod afterward, just clear the umask and remove the bits manually.
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.
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.
