Ah, right.

This can be shortened to:
while ((search = strstr(line, " with ")))
line = search + 1;
I still would have tripped over the +1 / -1, though. Calling an rfind()
or strrstr() or find_last() function that deals with it internally
would have helped me avoid that, I think, but we don't have use for such
a thing anywhere else.
