With the new expansion code (word splitting during instead of after other

The parsed internal representation of words consists of a byte string with a
list of nodes (commands in command substitution). Each unescaped CTLBACKQ or
CTLBACKQ | CTLQUOTE byte corresponds to an entry in the list.
If param in ${param#%##%%word} is not set, the word is not expanded (in a
deviation of POSIX shared with other ash variants and ksh93). Erroneously,
the pointer in the list of commands (argbackq) was not advanced. This caused
the wrong command to be executed later if the outer word contained another
command substitution.

If stdout isn't a tty, use unlimited width output rather than truncating to
79 characters. This is helpful for shell scripts or e.g., 'ps | grep foo'.
This hardcoded width has some history: In The Beginning of History[0], the
width of ps was hardcoded as 80 bytes. In 1985, Bloom@ added detection
using TIOCGWINSZ on stdin.[1] In 1986, Kirk merged a change to check
stdout's window size instead. In 1990, the fallback checks to stderr and
stdin's TIOCGWINSZ were added by Marc@, with the commit message "new
version."[2]
OS X Darwin has a very similar modification to ps(1), which simply sets
UNLIMITED for all non-tty outputs.[3] I've chosen to respect COLUMNS
instead of behaving identically to Darwin here, but I don't feel strongly
about that. We could match OS X for parity if that is desired.

However, the effect on security is little, since applications should not be

first place and other security-sensitive variables such as PATH should be

When using a new sh with an old (before 10.2) libc wordexp(), IFS is no

target. Due to a way issignal() selects the next signal to deliver
and report, if the simultaneous or already pending another signal
exists, that signal might be reported by the next waitpid(2) call.
This causes minor annoyance for debuggers, which must be prepared to
take any signal as the first event, then filter SIGSTOP later.
More importantly, for tools like gcore(1), which attach and then
detach without processing events, SIGSTOP might leak to be delivered
after PT_DETACH. This results in the process being unintentionally
stopped after detach, which is fatal for automatic tools.
The solution is to force SIGSTOP to be the first signal reported after
the attach. Attach code is modified to set P2_PTRACE_FSTP to indicate
that the attaching ritual was not yet finished, and issignal() prefers
SIGSTOP in that condition. Also, the thread which handles
P2_PTRACE_FSTP is made to guarantee to own p_xthread during the first
waitpid(2). All that ensures that SIGSTOP is consumed first.
Additionally, if P2_PTRACE_FSTP is still set on detach, which means
that waitpid(2) was not called at all, SIGSTOP is removed from the
queue, ensuring that the process is resumed on detach.
In issignal(), when acting on STOPing signals, remove the signal from
queue before suspending. Otherwise parallel attach could result in
ptracestop() acting on that STOP as if it was the STOP signal from the
attach. Then SIGSTOP from attach leaks again.
As a minor refactoring, some bits of the common attach code is moved
to new helper proc_set_traced().
