Thanks.  I have several comments about your Texinfo usage.

Please use "@itemize @minus"  and "@item" here, like this:

  There are two interesting points to be mentioned here.

  @itemize @minus
  @item
  The line number can be returned as ``0''.  The line number ``0'' means

etc., I hope you get the point.  The Texinfo translators, like
makeinfo and TeX, will then take care of producing the "-" before
every @item, and will also indent the list so it looks pretty.

Note two other changes I made in the original text: "0" should be
``0'', and there should be 2 blanks after each period that ends a
sentence.  These are basic rules of Texinfo and should be observed
throughout.

This sentence is confusing, I think: if I were a programmer of a front
end, I'd have hard time understanding what it means.  What ``line
number table'' are we talking about, and what does it mean that a PC
value ``does not belong'' to it?  Also, ``don't have a new starting
line'' is unclear, at least to me.

I think there's another noteworthy case where this happens: when
optimizations cause the code produced for some line be scattered
among the PC values.

Thanks again for taking time to write this up.
