build-first: window-specific variable

Default value: 0

Epsilon normally displays each window line by line, omitting lines that have not changed. When a command has moved point out of the window, Epsilon must reposition the display point (the buffer position at which to start displaying text) to return point to the window. However, Epsilon sometimes does not know that repositioning is required until it has displayed the entire window. When it discovers that point is not in the window, Epsilon moves the display point to a new position and immediately displays the window again. Certain commands which would often cause this annoying behavior set the build-first variable nonzero to prevent it.
