* 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
