It is used to avoid "var may be used uninitialized" warnings for some compilers. Officially (according to the C standard), it is undefined behavior. But I've observed considerable resistance by Junio to fix this properly. Therefore, unless you can show that your compiler generates unusable code you better live with the "self-initialization" warnings. -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
