Re: Can GIT_EXEC_PATH behave more like PATH?

I do not think it is useful at all.

I think GIT_EXEC_PATH is useful only in two occasions. (1) When Porcelains want to bypass "git" to avoid extra forking, it can ask where the executables are just once to "git --exec-path", and export GIT_EXEC_PATH with that single path; (2) When you want to try out a freshly built git without installing, you can export GIT_EXEC_PATH set, again with the single path that is where the build directory is. Neither wants a list of directories.

When users use "git frotz", the git command internally knows where the right version of subcommands are stored. When reason you would want to override that, you would exactly know one directory with which you want to override it. You do not want GIT_EXEC_PATH="/usr/lib/git-1.02:/usr/lib/git" in such a case, either.
