When a selection is active and the cursor is at the end of a line. Pressing the key 'End' do not clear the selection anymore (like it does in every other editor).

This look like a side effect of these commits:

Support camel-case for word-wise movement (87d8adb1c32c3008013b95ed2d6ff87e9a4d921a)
Extent camel-case cursor movement (d7516902c9234ad8a6a4c1919853e04adbcadf61)
Extent camel-case cursor movement (b14e54b4584d19c7c9a50b7d30eadd7e16299517)

A reverts these changes and the behavior return to what I expect.
