Dmytro Maluka 5510317942 Relocate buffer view when reloading file (#3250)
After reloading a file that has been externally modified, the buffer
view may become invalid: the displayed subset of lines of the file may
no longer exist, since the file may have been truncated. So relocate the
buffer view in this case.

In particular, this fixes crashes caused by out of bounds accesses to
the line array by displayBuffer() trying to display no longer existing
lines.
