Hello,

Per recent post to gdb@, the attached adds a libgdb chapter to the GDB
internals document.

Eli, in your original comments you mentioned more @node's. I'm not sure
that I follow - gdbint is very @node sparse only having them for @chapters.

I agree; I do not like the idea of this proposed
enhancement of finish. I think that if the source
looked like

foo (bar ());

and I stepped into bar, then said "finish", and
found myself in foo, I would find that confusing.
It would seem as if bar had been called from foo,
which is not the case.
