   An update that has three recommended fixes can now be
   installed.

Description:


   This update provides mksh R50f, which brings several fixes and
   enhancements:

   - Fix printing of negative integer values with 'print -R'. (bsc#1023419)
   - Make unset HISTFILE actually work. (bsc#1029664)
   - Do not permit += from environment. (bsc#1029664)
   - Handle integer base out of band like ksh93 does.
   - Protect standard code (predefined aliases, internal code, aliases and
     functions in dot.mkshrc) from being overridden by aliases and, in some
     cases, shell functions.
   - Implement GNU bash's enable for dot.mkshrc using magic aliases to
     redirect the builtins to external utilities; this differs from GNU bash
     in that enable takes precedence over functions.
   - Move unaliasing an identifier when defining a POSIX-style function with
     the same name into lksh, for compatibility.
   - Korn shell style functions now have locally scoped shell options.
   - Fix read -n-1 to not be identical to read -N-1.
   - Several fixes and improvements to lksh(1) and mksh(1) man pages.
   - Fix issues with IFS='\' read.
   - Fix integer overflows related to file descriptor parsing, reduce memory
     usage for I/O redirs.
   - Fix miscalculating required memory for encoding the double-quoted parts
     of a here document
     or here string delimiter, leading to a buffer overflow.
   - Add options -a argv0 and -c to exec.
   - Prevent use-after-free when hitting multiple errors unwinding.
   - Fix use of $* and $@ in scalar context: within [[ ... ]] and after case
     and in here documents.
   - Fix set -x in PS4 expansion infinite loop.
   - Fix rare infinite loop with invalid UTF-8 in the edit buffer.
   - Make the cat(1) builtin also interruptible in the write loop, not just
     in the read loop.
   - We use update-alternatives so there is no need to obsolete ksh.

   For a comprehensive list of changes please refer to the package's change
   log.
