So this is a good change. [Foornote] *1* The original motivation of "-S<block-of-text>" was to be a building block for the tool Linus dreamed in his message https://lore.kernel.org/git/Pine.LNX.4.58.0504150753440.7211@ppc970.osdl.org that explained why recording renames at the commit time is a bad idea. > " --pickaxe-all\n" \ > " show all files diff when -S is used and hit is found.\n" \ > " -a --text treat all files as text.\n"
