Log Message:
indent: replace unreachable code with assertions

The input buffer is always supposed to be terminated with a newline. The
function inbuf_read_line silently skips null characters. Since the input
buffer is redirected to a temporary buffer in some cases, do not simply
remove this supposed dead code, but replace it with assertions.

In any case, if the code for calling inbuf_read_line had been reachable
and actually allocated a different buffer, continuing to use the pointer
p would have invoked undefined behavior anyway.
