sh: Sync with FreeBSD:
* Expand assignment-like words specially for export/readonly/local.
* Remove unused variables.
* Reset pendingsigs before checking pending traps, not after.
* Track continued jobs (even if not continued by bg or fg).
* Inline waitproc() into its only caller.
* Fix EINTR race condition in "wait" and "set -T" using sigsuspend().
* use setinputfile instead of open/setinputfd.
* Prefer internal nextopt() to libc getopt().
* Use C99 flexible array instead of accessing array beyond bounds.
* Fix two issues when an alias is redefined.
* Detect and flag write errors on stdout in builtins.
* Prefer strsignal() to accessing sys_siglist directly.
* Don't lose $? when backquoted command ends with semicolon or newline.
* Fix crash when parsing '{ } &'.
* Pass $? to command substitution containing compound/multiple commands.
* Simplify cd-hash interaction.
* Remove mkinit's initialization routine.
* Move some stackmarks to fix high memory usage in some loops.
* Show negated commands (!) in jobs output.
* Prefer our character classification functions to <ctype.h>.
* Expand here documents in the current process.
* Do not test for digit_contig in mksyntax.
* Simplify mksyntax
* Fix a crash with the stackmark code.
* If a SIGINT or SIGQUIT interrupts "wait", return status 128+sig.
* When executing a trap, keep exit status along with evalskip.
* Update $FreeBSD$ to include SVN id.

sh: Add $'quoting' (C-style escape sequences).
A string between $' and ' may contain backslash escape sequences similar
to the ones in a C string constant (except that a single-quote must be
escaped and a double-quote need not be). Details are in the sh(1) man
page.
This construct is useful to include unprintable characters, tabs and
newlines in strings; while this can be done with a command substitution
containing a printf command, that needs ugly workarounds if the result
is to end with a newline as command substitution removes all trailing
newlines.
The construct may also be useful in future to describe unprintable
characters without needing to write those characters themselves in 'set
-x', 'export -p' and the like.
The implementation attempts to comply to the proposal for the next issue
of the POSIX specification. Because this construct is not in
POSIX.1-2008, using it in scripts intended to be portable is unwise.
Matching the minimal locale support in the rest of sh, the \u and \U
sequences are currently not useful.
