If the numeric argument passed to ash's 'shift' built-in is greater than
'$#' the command performs no operation and exits successfully. It should
return a non-zero exit code instead:

This is consistent with bash and hush.

Currently, it is impossible to pass more than one option to the isntall
script, so it totally prevents using --noclobber.

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

When grep is passed -r, recursive_action will treat any symlinks to
directories not in the root as normal files, since it lstat's them and
is therefore told they are not directories. However, file_action_grep
will still try to fopen and read from them to see whether they match,
which varies in behaviour across platforms. Linux will give EISDIR and
thus grep will not find any matching lines, but FreeBSD will give the
raw contents of the directory itself, which may match the given pattern.
Also, if grep is passed -c, it will even print a count for these
symlinks, even on Linux.
Since this recursive_action behaviour is required for the correct
functioning of other applets, such as tar, grep should handle this
special case and skip any such symlinks.

The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to
setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously,
RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542
re-purposed IPV6_PKTINFO when given to setsockopt. The special
Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO
in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO.
Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC
3542 style, and if not, we assume that only the RFC 2292 API is
available, using IPV6_PKTINFO for both.

Platforms differ on what their implementations of statfs include.
Importantly, FreeBSD's does not include a f_frsize member inside struct
statfs. However, statvfs is specified by POSIX and includes everything
we need, so we can just use that instead.

This patch only affects prompts with newlines.
We redraw the prompt [+ input] occasionally, e.g. during tab completion,
history browsing or search, etc, and we expect it to align with prior
redraws, such that the visible effect is that only the input changes.
With multi-line PS1, redraw always printed the prompt some lines below
the old one, which resulted in terminal scroll during every redraw.
Now we only redraw the last PS1 line, so vertical alignment is easier to
manage (we already calculated it using only the last line, but re-drew
all lines - that was the culprit), which fixes those extra scrolls.
Notes:
- We now use the full prompt for the initial draw, after clear-screen (^L),
and after tab-completion choices are displayed. Everything else now
redraws using the last/sole prompt line.
- During terminal resize we now only redraw the last[/sole] prompt line,
which is arguably better because it's hard to do right (and we never did).
- Good side effect for reverse-i-search: its prompt now replaces only the
last line of the original prompt - like other shells do.
