This function was used only for parsing the hunk headers generated by xdiff. Now that we can use hunk callbacks to get that information directly, it has outlived its usefulness. Note to anyone who wants to resurrect it: the "len" parameter was totally unused, meaning that the function could read past the end of the "line" array. In practice this never happened, because we only used it to parse xdiff's generated header lines. But it would be dangerous to use it for other cases without fixing this defect.
