When getopt32() has complementary options it's possible to specify
the minimum and maximum number of arguments allowed. Checking
these values was inconsistent:
- '?' correctly checked that it was followed by a digit but set
the otherwise unused spec_flgs variable on error.
- '=' failed to check that it was followed by a digit.

Commit fd47f0567 (lineedit: print prompt and editing operations
to stderr) changed various print statements to output to stderr.
The change in show_history() caused the shell history builtin to
send its output to stderr.
Revert that part of the commit.

POSIX generally requires normal output to go to stdout and
diagnostic (i.e. error) output to go to stderr.
When usage messages for BusyBox applets are specifically requested
by the user (e.g. 'find --help') they should go to stdout; when
they're emitted due to an error they should go to stderr.

There are two calls to dup2() in busybox_main(). These were
introduced to coerce full_write2_str() into writing to stdout.
The relevant commits were: 21278dff7 (busybox: do not print help
to fd 2, print it to fd 1) and 5a7c72015 (busybox --list option.
+140 bytes. Rob wanted it.)
Later, in commit 729ecb87b (bbconfig: make it independent from
printf functions), the function full_write1_str() was added.
Using this in busybox_main() allows us to drop the dup2() calls.

Although "naive" counting function is not too slow and is smaller,
using it on e.g. each of 1024 words of CPU mask feels wrong.

When icanon is set with -echo (e.g. ssh from an emacs shell) then
S.state will remain null but later it will be deferenced causing ash to
crash. Fix: additional check on state.

Commit 8baa643a3 (lineedit: match local directories when searching
PATH) included subdirectories of the current directory in the search
when tab-completing commands.
Unfortunately a short time later commit 1d180cd74 (lineedit: use
strncmp instead of is_prefixed_with (we know the length)) broke
this feature by returning an incorrect length for the array of paths.
Fix the length and reinstate matching of subdirectories.

Running an applet with '--help' as its only argument is treated
as a special case. If additional arguments follow '--help' the
behaviour is inconsistent:
- applets which call single_argv() print help and do nothing else;
- applets which call getopt() report "unrecognized option '--help'"
and print help anyway;
- expr says "expr: syntax error" and doesn't print help;
- printenv silently ignores '--help', prints any other variables
and doesn't print help;
- realpath says "--help: No such file or directory", prints the path
of any other files and doesn't print help.
If the first argument is '--help' ignore any other arguments and print
help. This is more consistent and most likely what the user wanted.
See also commit 6bdfbc4cb (libbb: fix '--help' handling in
FEATURE_SH_NOFORK=y).
