There are certain house-keeping tasks that need to be performed at the very beginning of any Git program, and programs that are not built-in commands had to do them exactly the same way as "git" potty does. It was easy to make mistakes in one-off standalone programs (like test helpers). A common "main()" function that calls cmd_main() of individual program has been introduced to make it harder to make mistakes. * jk/common-main: mingw: declare main()'s argv as const common-main: call git_setup_gettext() common-main: call restore_sigpipe_to_default() common-main: call sanitize_stdfds() common-main: call git_extract_argv0_path() add an extra level of indirection to main()
