! HB_DIRADDPATHSEP() fixed to not add pathsep to plain dirspec.
! HB_DIRDELPATHSEP() fixed to not remove double pathspec from UNC root.
! Fixed to work if HB_OSDRIVESEPARATOR()'s length is not 1:
HB_PATHMAKERELATIVE(), HB_DIRUNBUILD(), HB_DIRDELPATHSEP().
(QUESTION: is this a valid possibility, or is this over-design?)
+ Added TODO to HB_CWD() to also be able to change dir.
This will require adding Harbour versions of DIRCHANGE() and
DISKCHANGE(), or moving the implementation to C level.
(possibly the latter)
- Deleted HB_FNAMEDIREXTSET(). Doesn't satisfy a general need.
