Justin M. Keyes c049b8f002 fix(bufwrite): abort :write if Progress handler changes the buffer #42464
Problem:
If a Progress handler changes the buffer during a slow `:write`, the
written file mixes old and new lines, or gets "???" lines (E315) if
lines were deleted. 89e915b67a only keeps 'modified'.

Solution:
Abort the write with E787 and restore the original file ('writebackup').
