[PATCH v5 02/15] diff --color-moved: clear all flags on blocks that are too short

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Phillip Wood <phillip.wood@xxxxxxxxxxxxx>

If a block of potentially moved lines is not long enough then the
DIFF_SYMBOL_MOVED_LINE flag is cleared on the matching lines so they
are not marked as moved. To avoid problems when we start rewinding
after an unsuccessful match in a couple of commits time make sure all
the move related flags are cleared, not just DIFF_SYMBOL_MOVED_LINE.
