Emacs already does all that, of course.  Just not in the case of the
menu entries, where the node names are not expected to span more than
one line.

As I said, maybe.  But the fact is that the _Texinfo_source_ of the
Texinfo manual uses different amounts of blanks in this node's name.
So line breaking and filling in the Info file is not the issue here.

The problem is _inconsistency_, not extra blanks.  The number of
blanks should have been consistent in all the uses of this node name.
