As the format HAS ALREADY lasted for a long time since its introduction in d8f4790e (diff-tree --cc: denser combined diff output for a merge commit., 2006-01-24), it is too late to change the default. If a scripted use wants to parse out all the pathnames, it can write the option on the command line just once in the script file and forget about it. For interactive use, the standard answer is "you can alias only for yourself in ~/.git/config", but unfortunately, because the alias works at the command level (e.g., an alias that allows "git lc" to work as "git log --cc --combined-all-paths" can be written), an optional behaviour like --combined-all-paths that is shared across a family of commands (e.g., "log" and "show" both would benefit) is a bit awkward to handle. I wonder if introducing an "aliases for options" mechanism would improve the situation. Take an otherwise unused character sequence, say, cccc, and when you say "git <cmd> --cccc", pretend as if you said "git <cmd> --cc --combined-all-paths" from the command line.
