Thanks to Cristian Ionescu-Idbohrn for noticing.
Also fix "%d" ' 42' to skip leading whitespace.

When deleting a directory, the directory should not be removed if the
file in the subdirectory fails to be deleted.
Background information:
When I tested the kernel using LTP (linux-test-project).I found the
mv command have some issue. The LTP test case use the mv command to
move the directory t1 in the cgroup file system to the /tmp directory.
becase files in the cgroup file system are not allowed to be removed.
so the mv reported "Permission denied", but I used the ls command to
view the results and found that the directory t1 had been removed
from the cgroup file system. For the same test case, I used the mv
tool in the GNU coreutils, and the directory t1 will not be removed.
the following testcase use busybox mv:
/ # mount -t cgroup -o cpu cgroup /cpu
/ # cd /cpu
/cpu # mkdir -p t1
/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat t1
cgroup.procs cpu.cfs_quota_us notify_on_release tasks
cgroup.sane_behavior cpu.shares release_agent
/cpu # mv t1 /tmp
mv: can't remove 't1/cgroup.procs': Operation not permitted
mv: can't remove 't1/cpu.cfs_period_us': Operation not permitted
mv: can't remove 't1/cpu.stat': Operation not permitted
mv: can't remove 't1/cpu.shares': Operation not permitted
mv: can't remove 't1/cpu.cfs_quota_us': Operation not permitted
mv: can't remove 't1/tasks': Operation not permitted
mv: can't remove 't1/notify_on_release': Operation not permitted
mv: can't remove 't1/cgroup.clone_children': Operation not permitted
/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat cgroup.procs
cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior
cpu.shares release_agent
/cpu #
This patch fixed it, don't call rmdir if remove_file return failure,
and under certain file systems, the mv could work normally.

This necessitates switch from libc FILE api to a simple
homegrown replacement.
The change which fixes the bug here is the deleting of
restore_redirected_FILEs();
line. It was prematurely moving (restoring) script fd#3.
The fix is: we don't even _want_ to restore scrit fds,
we are perfectly fine with them being moved.
The only reason we tried to restore them is that FILE api
did not allow moving of FILE->fd.

Kconfig-language.txt was deleted in commit 4fa499a17b back in 2006.
Move to docs/ as suggested by Xabier Oneca:
http://lists.busybox.net/pipermail/busybox/2014-May/080914.html
Also update references to it everywhere.

This fragment did not work right:
temp = bb_get_chunk_from_file(fp, &len);
if (temp) {
/* len > 0 here, it's ok to do temp[len-1] */
char c = temp[len-1];
With "int len" _sign-extending_, temp[len-1] can refer to a wrong location
if len > 0x7fffffff.

This makes size display 5-char wide instead of 6-char, but now it's smarter
(can show sizes in "12.3M" format).
