Vim mode g<c-a> stopped working

[saecki]

Description

In vim mode it was preoviously possible to select a bunch of numbers in visual block mode by pressing <c-v>, and then incrementing them all by pressing g<c-a> resulting in the following edit

Before:

0
0
0
0
0

After:

1
2
3
4
5

In normal mode <c-a> still works as expected.
In visual mode just pressing <c-a> does nothing, and pressing g<c-a> highlights the whole document.
