* utils/hbmk2/hbmk2.prg
    + added help and Markdown output for hbrun mode,
      using same options as in hbmk2 mode, run 'hbrun -help'
    + documented how to disable hbrun history
    + documented script search and and script autodetection details
    + documented opening .dbf files
    + documented how to paste text into shell prompt
    + documented limitation that in script INIT PROCEDUREs,
      automatic selection of interactive GT doesn't work
    + __Accept(), __Wait() to trigger interactive GT in scripts

  * src/rtl/objfunc.prg
    ! __objGetMsgList(): fixed to not rely on any assumption
      about the collation. In UTF8EX mode it was always
      returning empty array.
      Plus cleanup/optimizations

  * contrib/xhb/hbxml.c
    ! fix to a memory double free
      Thanks to Jose F. Gimenez for the patch.

  * contrib/hbtest/core.prg
  * contrib/hbtest/tests/test.prg
  * contrib/hbamf/tests/test.prg
    + added support and tests for tests returning
      array, hash and object types
    * changed zero byte to be escaped to \0 (was \000)
    + added memo tests and related engine cleanups

  * src/rtl/valtoexp.prg
    + hb_ValToExp(): output for objects changed to use double
      quotes for strings instead of a mixture of double/single
      ones, to make it easier stringifying the result

  * src/rtl/hbfilehi.prg
    % hb_DirSepDel(): minor optimization

  * tests/fixcase.hb
    + correct casing of EXTERN/REQUEST references

  * contrib/hbwin/tests/olesrv4.prg
  * contrib/hbxpp/hbxpp.ch

    ! run fixcase.hb to format REQUEST/EXTERNs

  * contrib/hbmisc/spd.c
  * contrib/hbmisc/hbnf.hbx
    ! missing casing for one function

  + tests/extend1.hbp
  * tests/extend1.prg
  * tests/extend2.c
    ! fixed to build and run again under Harbour

  * tests/debug.prg
  * tests/dynobj.prg
  * tests/for2.prg
  * tests/memvar.prg
  * tests/ppapi.prg
  * tests/scroll.prg
  * tests/set.prg
  * tests/str.prg
    * __Accept() changed to WAIT or Inkey( 0 )

  - contrib/hbrun/hbrun.1
  * config/postinst.hb
    * deleted hbrun's (outdated) man doc.
      Now built into hbmk2.prg as hbrun help.

  * contrib/hbmisc/hb_f.c
  * contrib/xhb/tests/xml1.prg
  * tests/hrbext.prg
    * comment/minor update

  * tests/hrb.prg
  * tests/hrbext.prg
    + hrb.prg to create .hrb file if it doesn't exist
    + added INIT PROCEDURE
