xdiff: fix merging of appended hunk with -W
When -W is given we search the lines between the end of the current context and the next change for a function line. If there is none then we merge those two hunks as they must be part of the same function. If the next change is an appended chunk we abort the search early in get_func_line(), however, because its line number is out of range. Fix that by searching from the end of the pre-image in that case instead. Reported-by: Junio C Hamano <> Signed-off-by: Rene Scharfe <> Signed-off-by: Junio C Hamano <>
