    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.
