Instead of "replaced rectangle" I should have said "replacing rectangle".

Select a rectangle, with point at the lower right corner and mark at the upper
left.  Then C-x r t.  Type `EEE' as the string to replace each row of the
rectangle.

The cursor is left at the beginning, not the end, of the `EEE' string on the
last row.  IOW, a rectangle of E's replaces the selected rectangle, but point is
now at neither the upper left nor the lower right.

This can make a difference when combining such an action with other operations,
including other rectangle operations.  You should be able to do `C-x C-x' to
select the E's rectangle.  Instead, you get the region from the first E to the
first E in the last row, which corresponds to an empty rectangle (no width).
