* source/rtl/tbrowse.prg
! I've fixed all known (to me) issues with latest TBrowse code.
::HitTop/Bottom were set back to .F. if a ::RefreshAll() was issued. This is wrong since only
movement keys can reset them.
Issuing a long sequence of K_UP/K_DN (or CTRL_...) resulted on wrong movement of datasource (you could
even go backward using K_DN :-O)
You could get an out of bounds moving around inside tbrowse.
* Note that original Clipper TBrowse caches displayed rows, so moving left or right does not require
calling ::Skipblock to refresh screen. Present implementation of TBrowse has not such a cache so
a lot more of skipping around is needed.
