[PATCH v4 1/3] diff: avoid redundantly clearing a flag

[Jonathan Tan]

No code in diff.c sets DIFF_SYMBOL_MOVED_LINE except in
mark_color_as_moved(), so it is redundant to clear it for the current
line. Therefore, clear it only for previous lines.

This makes a refactoring in a subsequent patch easier.
