in GridText.c:

        if ((ebuf = readEditedFile(ed_temp)) != 0) {
             * Only use the first line of the result, and only that up to
             * the size of the field.
            for (p = ebuf; *p != '\0'; ++p) {
                if ((p - ebuf) >= form->size - 1) {
                    *p = '\0';
                } else if (*p == '\n' || *p == '\r') {
                    *p = '\0';
            StrAllocCopy(form->value, ebuf);

(taking out the limit based on form->size sounds okay to me)
