58b578bfb0 mksh: Import unpacked mksh-59b sources.
Two patches have been applied on top, both of which are stored in the
patches directory as manual-Build.sh and manual-funcs.c, to fix issues
on Darwin and SunOS that will be included in the next mksh release.  The
binary mksh.ico file has been manually removed.

This paves the way for  mksh to be used as an alternate bootstrap shell
instead of shells/pdksh, which has been unmaintained for many years and
has some known issues.

Initial bulk build results on Darwin and SunOS look good, and having a
maintained shell which focuses on portability and speed should provide
us with a better long-term option for systems which require a bootstrap
shell.

d14aaec565 Update mksh to R48b.
Changes:

R48b is a minor bugfix update:

[tg] Fix display issue with multi-line prompts and SIGWINCH

R48 is a small but important bugfix update:

[tg] dot.mkshrc: unbreak hd(1) function in UTF-8 mode
[Jens Staal, tg] Improve buildability on Plan 9 and support kencc
[tg] Clean up and improve build process and testsuite
[Michael Langguth] Add multi-layer ICO file from mksh/Win32
[tg, Steffen Daode Nurpmeso] Fix interactive shell exiting on ^C or
syntax error when the EXIT pseudo-signal trap was set (to anything)
[tg, Daode] Display longer command excerpts in job control
[tg] Rewrite Emacs mode display window sliding calculation code
[tg] dot.mkshrc: “doch” now keeps standard input
[tg] Reduce memory usage and improve comments and documentation

R47 is a bugfix everyone must upgrade to:

[tg] Do not accidentally remove lksh.1 for in-srcdir builds
[tg] Fix post-build non-‘-Q’ output for lksh
[tg] Silence some configure-time warnings for clang-3.2 and GCC
[tg] Prevent recursion loops for namerefs; found by ormaaj
[tg] Replace wcwidth code by mine based on Unicode 6.2.0
[tg, Alexander Polakov] Fix quoting in word part of ${var+word} etc.
when the expression is in a quoted brace or a here document
[tg] Fix some compiler warnings; improve sig{,handler}_t detection
[tg] Keep SIGCHLD blocked in some more semi-critical code paths
[tg] Fix uninitialised variable causing random nōn-numerical input to be
accepted and acted upon in the select built-in command
[tg] No longer chown(2)/chmod(2) the -T tty(4) argument
[tg] Don’t fork(2) if the -T tty(4) argument begins with ‘!’; eliminates
the need for things like oneit_line/cttyhack/etc. on Linux
[jca] Fix “for var in; do” to not be interpreted as “for var; do”
[tg] Use %zu for printing size_t (ipv %lu with casting around)
[tg] use ${SIZE-size} for lewellyn’s cross
[fgsch, espie, millert, tg] Write more testcases
[millert] POSIX specifies that for && and || lists, only the exit status
of the last command matters for “set -e”; fix and document
[millert] check.pl: Add -T flag to set the tmpdir; use mkstemp(3) and
mkdtemp(3) instead of $$ in /tmp for tempfiles
[jca] Make $(<nonexistent) behave like $(cat nonexistent)
[tg] Let shf_open return an errno; display why file wasn’t read
[tg] Finally decide on regression-39 desired outcome (sync with AT&T
ksh93 and GNU bash --posix as well as mksh behaviour)
[tg] Fix post{in,de}crement in not evaluated side of e.g. ternary operator (LP#1187729)
[tg] Fix “set -x” problems; add “set +o inherit-xtrace” (LP#1179287)
[tg] Simplify some code
[tg] Fix segfault related to mixing funsub/valsub and comsub

R46 delivers these changes:

[tg] dot.mkshrc: prevent lksh from running it
[tg] Add the lksh manual page to the mksh distribution
[tg] Make both lksh and mksh interpret numbers with a leading digit zero
(‘0’) as octal precisely iff “set -o posix” is active
[tg] Point out the octal digit and the integer arithmetic differences
from POSuX verbosely in the manual pages (point people who need octals
to “set -o posix” and who need longs to lksh) and elaborate on the
horrors of ISO C Undefined Behaviour which is allowed to delete all your
data
[tg] Unbreak “set -o” (list flags) in lksh on LP64 machines
[tg] Implement Emacs mode PgUp as Vi insert mode Cur↑ for Yofuh
[tg] Allow setting both “set -o sh” and “set -o posix”, if done in the
same command; shuffle around compatibility levels (mksh/lksh, with -o
sh, with -o posix) again; permit a /bin/sh to set either or both
[tg] Sync lksh manual page with the exact code ifdefs
[tg] Change more use of signed integer to use unsigned instead
[tg] Implement “set -o pipefail” like AT&T ksh93 and GNU bash do
[tg] dot.mkshrc: provide hd(1) in Pure mksh™ for fallback
[tg] Implement VALSUBs (value substitutions): ${|REPLY=foo;}

c1f91161ba Update to mksh-45.
* [tg] Make “set -x” print the commands run in escaped form
* [tg] PS4 in dot.mkshrc is now timestamped
* [tg] The &> GNU bash I/O redir is no longer parsed in -o posix, -o sh modes,
  lksh (breaks valid scripts)
* [tg] Implement ${ …;} more efficiently (deleted-open files)
* [tg] For shf, %#s (if you can get it past GCC’s printf format attribute)
  calls print_value_quoted, ignoring field width and precision
* [tg] Catch “typeset =” (regression) with better error message
* [tg, Tonnerre Lombard] add “doch” alias to dot.mkshrc which just repeats the
  last input line with sudo(8)
* [tg] Use unsigned integers for all calculations, to avoid ISO C “Undefined
  Behaviour” (and implementation-defined behaviour) throughout (most of) the
  code; emulate signed integer arithmetics using unsigned; not-lksh only
* [tg] Emulate signed modulo naïvely, for correct sign of the result
* [tg] Add <<< and >>> for ROL and ROR (rotate left and right, respectively)
  operations, <<<= and >>> assignments; bitwise AND the RHS of a shift/rotate
  op with 31 (not for lksh)
* [tg] Remove a warning by working around a workaround found in dietlibc which
  works around a bug in broken software such as GNU tar (really!)
* [tg] Correct and simplify list and categorisation of built-in commands as
  POSIX special and “everything else” plus a flag to keep assignments
* [tg] Handle ((foo)) as “let]” internally to avoid a conflict with
  user-defined functions called let (LP#1156707)
* [tg] Clean up the code
