From fab01ec52e83df886ca952879e196b8d8bd42013 Mon Sep 17 00:00:00 2001 From: Phillip Wood Date: Tue, 4 Sep 2018 14:52:58 +0100 Subject: diff: fix --color-moved-ws=allow-indentation-change If there is more than one potential moved block and the longest block is not the first element of the array of potential blocks then the block is cut short. With --color-moved=blocks this can leave moved lines unpainted if the shortened block does not meet the block length requirement. With --color-moved=zebra then in addition to the unpainted lines the moved color can change in the middle of a single block. Fix this by freeing the whitespace delta of the match we're discarding rather than the one we're keeping.
