Because you only need "diff --line-prefix" to work while leaving "log --line-prefix" broken for the purpose of your immediate purpose to update "diff/log [--graph and other options] --submodule=<type>" to show "diff A B" in the submodule, I think it is OK to leave it broken, as long as it is clearly documented that "--line-prefix" should also apply to the log message part but the current code doesn't. Eventually, when somebody wants to add a new <type> that runs "log -p A..B" instead of "diff A B" in submodules and wants to make it interact well with "log --graph" at the superproject level, they need to fix the breakage you leave behind. That would be much better than "because I cannot figure out how to prefix on the log part, I'll name this --diff-line-prefix", which will force us to support that half-baked option forever while having to add a proper "--line-prefix" eventually anyway. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
