This is not an Emacs bug, it's a bug in the Texinfo manual.  For some
reason, it sometimes refers to this node as "@-  @hyphenation" (with 2
spaces), and sometimes as "@- @hyphenation" (with only 1 space).  The
menu uses the former, while the node name uses the latter.  So Emacs
cannot find the node.

That's because the command bound to '3' normalizes the whitespace in
the node name.  I don't know why it does that, but that code exists
since about forever.

Maybe we could consider normalizing the whitespace in the 1st case as
well, but that's just a work around for a buggy manual.
