Release 1.0.6

Sooner than expected after the fifth, here is the sixth ksh
93u+m/1.0 bugfix release. 93u+m/1.0.5 brought a wide range of
bugfixes and robustness enhancements, but also introduced a serious
regression in pathname expansion, so that previous release is
WITHDRAWN and should not be used.

Main changes between ksh 93u+m/1.0.5 and 93u+m/1.0.6:

- Fixed a serious regression in pathname expansion where quoted
  wildcard characters were incorrectly expanded if a pattern
  contains both a brace expansion and a variable expansion.
- Fixed a bug where the command to launch a full-screen editor
  (^X^E in emacs and 'v' in vi) could cause the wrong command line
  to be edited if two shell sessions share a .sh_history file.

Main changes between ksh 93u+m/1.0.4 and 93u+m/1.0.5:

- Fixed various bugs causing crashes.
- Fixed many bugs in the emacs and vi line editors, in command
  completion, and in file name completion.
- Fixed various bugs in the handling of quotes, backslash escapes
  and braces when processing shell glob patterns (e.g. in pathname
  expansion and 'case').
- ksh now throws a panic and exits if a read error (such as an I/O
  error) occurs while trying to read the next command(s) from a
  running script.
- Fixed many bugs in 'printf' and 'print -f' built-in commands,
  including:
  . Multiple bugs causing incorrect output for relative date
    specifications, e.g., printf %T\\n 'exactly 20 months ago' now
    outputs a correct result.
  . More printf bugs with mix and match of % and %x$.
  . A data corruption bug when using %B with 'printf -v varname'.
  . A bug causing double evaluation of arithmetic expressions.
- Fixed a bug where 'unset -f commandname', executed in a subshell,
  hides any built-in command by the same name for the duration of
  that subshell.
- Fixed ${var/#/string} and ${var/%/string} (with anchored empty
  pattern) to work as on mksh, bash and zsh; these are no longer
  ineffective.
- Fixed incorrect result of array slicing ${array[@]:offset:length}
  where 'length' is a nested expansion involving an array.
- Command names can now end in ':' as they can on other shells.
- Fixed a spurious syntax error in compound assignments upon
  encountering a pair of repeated opening parentheses '(('.
- Fixed spurious syntax error in ${parameter:offset:length}: the
  arithmetic expressions 'offset' and 'length' may now contain the
  operators ( ) & |.
- Fixed a parsing bug in the declaration of .sh.math.* arithmetic
  functions.
- Fixed nameref self-reference loop detection for more than two
  namerefs.
- Several improvements to the POSIX compatibility mode.
- Many more minor and/or esoteric bugfixes.
