baa41c7855 ash: make ${v:N:M} more robust for very large M by clamping to MIN/MAX_INT 
Before this patch, "${v:2:0x100000001}" = "${v:2:1}",
and similarly, constructs like "${v:2:9999999999}" may give wrong result
due to int overflows.

4261341281 umount: ignore -c 
"-c, --no-canonicalize: Do not canonicalize paths."

As busybox doesn't canonicalize paths in the first place it is safe to ignore
this option.

return a non-zero exit code instead:

This is consistent with bash and hush.

8d8ee910f0 env: -u option fails due to typo 
The -u option is supposed to be allowed to appear multiple times; the
option string supplied to getopt32long requires it to be followed by a
nonnegative integer.

c6f213ade4 unzip: fix content listing and filtering when -j is used 
Original Info-ZIP's unzip uses unstripped filenames
while doing content listing and filtering, i.e.
 - in content listing mode -j is ignored completely
 - filtering is applied to non-stripped names, -j
   takes effect first while extracting the files

997ad2c64a strips path
components a little bit too early resulting in behavior
deviations.

Fix it by doing stripping after listing/filtering.

p.s. Info-ZIP's unzip behavior is the same as
     that of tar in --strip-components=NUM mode
