These functions transform an existing argv into one suitable for exec-ing or spawning via git or a shell. We can use an argv_array in each to avoid dealing with manual counting and allocation. This also makes the memory allocation more clear and fixes some leaks. In prepare_shell_cmd, we would sometimes allocate a new string with "$@" in it and sometimes not, meaning the caller could not correctly free it. On the non-Windows side, we are in a child process which will exec() or exit() immediately, so the leak isn't a big deal. On Windows, though, we use spawn() from the parent process, and leak a string for each shell command we run. On top of that, the Windows code did not free the allocated argv array at all (but does for the prepare_git_cmd case!). By switching both of these functions to write into an argv_array, we can consistently free the result as appropriate.
