coredump: kill cn_escape(), introduce cn_esc_printf() The usage of cn_escape() looks really annoying, imho this sequence needs a wrapper. And it is buggy. If cn_printf() does expand_corename() cn_escape() writes to the freed memory. Introduce cn_esc_printf() which hopefully does this all right. It records the index before cn_vprintf(), not "char *" which is no longer valid (in general) after krealloc().
