Hi,

when renaming a local variable, the names were changed inconsistently leading to incorrect code.

The problem was triggered by accident: first I pressed Ctrl-R, but I did not notice that these litte squares appear and
that I can just type in the new name. So I right-clicked to get Refactor/Rename... from the context menu. After renaming
with the dialog, e.g. from "a" to "au", the first appearance was renamed correctly, but the further appearances were
renamed to "auau".

The little-square renaming should probably be canceled automatically before the menu-renaming starts.

Best wishes,

Alexander
