I think it makes sense.

There is one thing I am not sure about, though. In your patch,
you still add the end-of-sequence marker. So you eliminate the
empty line 58, but keep it's associated line 0 entry. I guess
we have to in the following case:

  line 57 @ 0x1234
  line 58 @ 0x1240
  line 0  @ 0x1240

We need this because otherwise we'd record the wrong end-address
for line 57.

So I agree the patch makes sense, and I prefer it to be independent
of the debugging info.
