This option reduces decompression time by about 25% at the cost of
a 1K bigger binary.
config FEATURE_PATH_TRAVERSAL_PROTECTION
bool "Prevent extraction of filenames with /../ path component"

help
busybox tar and unzip remove "PREFIX/../" (if it exists)
from extracted names.
This option enables this behavior for all other unpacking applets,
such as cpio, ar, rpm.
GNU cpio 2.15 has NO such sanity check.
# try other archivers and document their behavior?
