    less: Update to version 458
    
    Version 458 was released on 4 APR 2013.  Differences since version 451:
      * Allow backslash escaping of metacharacters in LESS environment
        variable after the --use-backslash option.
      * Don't quit if syntax errors are found in command line options.
      * Increase sizes of some internal buffers.
      * Fix crash with "stty rows 0".
      * Fix display bug when using up/down arrow on the command line.
    
    Version 451 was released on 4 SEP 2012.  Differences since version 444:
      * Add ESC-F command to keep reading data until a pattern is found.
      * Use exit code of LESSOPEN script if LESSOPEN starts with "||".
      * When up/down arrow is used on the command line immediately after
        typing text, the next command starting with that text is found.
      * Add support for GNU regex.
      * Add configure option --with-regex=none and fix compile errors
        when compiling with no regex library.
      * Fix possible crashes caused by malformed LESSOPEN or
        LESSCLOSE variables.
      * Fix bug highlighting text which is discontiguous in the file
        due to backspace processing.
      * Fix bug in displaying status column when scrolling backwards
        with -J and -S in effect.
