view.
Change-Id: Icfbd3eb4e24cce3e1690e7eaf12e14e5705c7e3e
Adds two buttons to appear in context control lines in diffs. Whereas
the main button in a context control replaces the control with *all* of
the diff content that was collapsed into it, the new buttons will
instead display 10 lines of diff content either at the start or at the
end of the collapsed area.
If the number of lines collapsed into the context control are fewer than
11, the +10 buttons are not displayed.
