Doing so would mean that a version of Git that does not support a magic signature '#' will allow people and scripts to use ":/#abc" with such a meaning, and will prevent us from using '#' as a new magic signature with some useful meaning in the future. Rather, we need to force them to always spell it as ":/:#abc" even in the version of Git before the magic signature '#'. And the phrasing 'if the pattern begins with a character that cannot be a "magic signature" and is not a colon' needs to be clarified to avoid that misinterpretation for that reason. -- 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
