Fix line start and line end key binding behaviour

Browse Source 
Another fix for the key navigation behaviour around the zeroeth
glyph in the layout.

This commit adds a fast path for for the zero index when the
cursor position is set as zero, in case we are using the line-start
or line-end key bindings, similarly to what we did in commit
be64cbcdc22952ce2fa9f902e153e3bd9f4a08c9 for the move-up and
move-down bindings.
