I can't say anything about what is appropriate (or useful) for the MI
interface but I can tell you what's going on. This matches the
structure of the internal line table precisely.
- line 0 means end-of-sequence. I.E. PCs greater than 0x8048406 that
don't have a new starting line do not belong to this line number table.
- duplicated line numbers are emitted by the compiler to mark, mostly,
the ends of prologues. Sometimes the prologue is zero-sized.
