The reason I didn't do so is that it would make the line above 80
characters. So the alternatives to my current patch would be:
for (p = next = language; next && *len_ptr < 255 / 4 * 4;
p = next + 1) {
or
for (const char *p = language, *next = p;
next && *len_ptr < 255 / 4 * 4; p = next + 1) {
or factoring out writing the ISO 639 language descriptor into a function
of its own or just ignoring the 80 chars line limit. What do you prefer?
