0. emacs -Q
1. C-h r (if emacs is installed, otherwise `C-u h i /path/to/emacs.info
   RET')
2. Repeat `C-n' until the cursor is on the '*' before the first menu
   item 'Distrib'.
3. Type TAB
=> The cursor jumps over 'Distrib' and goes to the second menu item
   'Intro'.

The same thing happens if the cursor is on the space between '*' and
'Distrib' and you then press TAB.  In both cases, I expected the cursor
to go to the immediately following link instead of skipping it.  This
behavior annoys me every time I run into it, but I haven't debugged it
till now.  The attached patch fixes it.  (The code responsible for the
current behavior in Info-next-reference has not changed since the
command was added to Emacs, but I hope you'll nevertheless agree it's a
bug.)
