Fix off-by-one in extend_line_above (#3689)
`extend_line_above` (and `extend_line` when facing backwards) skip
a line when the current range does not fully cover a line.
Before this change:
foo
b#[|a]#r
baz
With `extend_line_above` or `extend_line` selected the line above.
#[|foo
bar]#
baz
Which is inconsistent with `extend_line_below`. This commit changes
the behavior to select the current line when it is not already
selected.
foo
#[|bar]#
baz
Then further calls of `extend_line_above` extend the selection up
line-wise.
