I could argue that using 2 sentences with 2 spaces between them as a
node name is a minor bug in the Bison manual (which, btw, is still not
fixed in the latest version 2.5).

As I responded there, the answer is YES.  The Info reader
canonicalizes the whitespace in a node name before it uses it for
search, and it also searches in a way that ignores excess whitespace
in the target string.
