So now everything is clear: this is a bug in Texinfo 4.8 that is fixed
in later versions.  The bug is triggered by this trickery in the
manual's sources:

  @defvar minibuffer-local-map
  This
  @anchor{Definition of minibuffer-local-map}
  @c avoid page break at anchor; work around Texinfo deficiency
  is the default local keymap for reading from the minibuffer.  By
  default, it makes the following bindings:

Evidently, makeinfo 4.8 leaves an empty line where there was the
@anchor.  The @anchor was put in this strange place to make sure the
page break is not inserted in the printed manual, thus making the
cross-references to it point to the wrong page.  I don't know if this
trickery is still needed nowadays.
