add.c: extract check_path_for_gitlink() from treat_gitlinks() for reuse
Extract the body of the for loop in treat_gitlinks() into a separate check_path_for_gitlink() function so that it can be reused elsewhere. This paves the way for a new check-ignore sub-command. Also document treat_gitlinks(). Signed-off-by: Adam Spiers <git@adamspiers.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
