I believe we made the Emacs Info reader robust enough to handle
both old and new formats of preamble.  Regarding the option
--strict-node-location in the standalone Info reader,
we could create a similar option in the Emacs Info reader
with a name like `Info-strict-node-location', but I doubt
that many users might want to use it since it's intended
for debugging, and Emacs has a built-in debugger for that.
