   -  CHG: CHANGE OF DEFAULT OUTPUT OF: xhexfind, hexfind
           if a full /fromtext/totext/ pattern is given
           the hexdump output now shows the replaced
           output text by default. use option -dumpfrom
           to display the fromtext (search hits) in output.
   -  CHG: CHANGE OF SIMULATION OUTPUT OF: replace, xreplace, extract
           1. simulation mode now shows a hex dump by default
              instead of just statistics. use -nodump for
              the old behaviour.
           2. hex dump output now shows the replaced
              output text by default. use option -dumpfrom
              to display only the fromtext (search hits)
              as it was default before.
           option -yes behaves as always, not showing hexdumps
           but only statistics of the number of changes.
   -  CHG: STRICTER PATTERN PARSING WITH: replace, extract, xreplace
           a pattern like /from/to with missing "/" separator
           at the end now stops with an error.
   -  add: sfk rename, a flexible mass file rename
           using rename expressions.
   -  add: sfk xmlform: simple xml line text reformatter
           for convenient viewing.
   -  fix: linux default color with dark background:
           theme:black no longer uses grey but now the
           terminal default color by sequence {ESC}[0;0m
   -  fix: linux: gindex, iname used wrong home folder.
   -  fix: gindex: if user supplied relative dir names
           subsequent iname produced wrong results.
   -  fix: gindex: options -size or -qarc caused listing
           of wrong folders.
   -  add: snapto: option -raw to collect faster.
   -  chg: hexdump output colors reworked.
   -  chg: sfk cmd: now uses the actual current sfk binary name
           instead of just "sfk" for the created command
   -  fix: fromclip: crash on missing data.
   -  add: base+xd: demo of xreplace allowing output preview
           without writing to files.
   -  chg: sfk replace: unreadable files which are skipped
           no longer produce an error but a warning.
   -  chg: small syntax change: sfk chars now only accepts
           char or chars as command name.
   -  chg: help text: full rework of web references.
