ASMEDIT.INC (bug + solution)

with the original ASMEDIT.INC code,
after a "file/save", multi_BACK or multi_DELETE does not change the file "state" (modified/unmodified) ... the file keeps the unmodified state.

1) Put the caret in the middle of a line,
2) "delete" ... ok, the file state is modified
3) save/file ... ok, now the file state is unmodified
don't put back the focus on the line
but the caret is still on the line
4) "delete" again
bug, the file keeps the unmodified state !
(if "EXIT", the last changes are lost)

solution ---> (in fact, like "VK_SPACE" code)
