ksh 93u+m/1.0.7

[McDutchie]

Here is the seventh ksh 93u+m/1.0 bugfix release. It fixes a hang in command substitutions when combined with 'exec' and certain redirections.

Main changes between ksh 93u+m/1.0.6 and 93u+m/1.0.7:

• Fixed a hang in command substitutions (introduced in 93u+m/1.0.0) that was triggered when redirecting standard output within a command substitution, in combination with other factors. E.g., the following no longer hangs:
  { v=$(redirect 2>&1 1>&9); } 9>&1
• Fixed a crash on trying to append an indexed array value to an unset name reference, e.g.: nameref unsetref; unsetref+=(foo bar). This now produces a "removing nameref attribute" warning before performing the assignment.
• Fixed: assignments like name=(...) to arrays did not preserve the array and variable types; similarly, assigning an empty set () to a compound indexed array caused the -C attribute to be lost.
• Fixed incorrect rejection of the tab key while reading input using the read built-in command.
• Fixed a bug in printf %T: when using dates and times in the past, time zones for the present were incorrectly used, ignoring historical changes.
