Log Message:
indent: fix undefined behavior in buffer handling

Adding an arbitrary integer to a pointer may result in an out of bounds
pointer, so replace the addition with a pointer subtraction.

In the buffer handling functions, handle 'buf' and 'l' before 's' and
'e', since they are pairs.

In inbuf_read_line, use 's' instead of 'buf' to make the code easier to
understand for human readers.

No functional change.
