problems with display of info files in emacs

[Rubey Martin]

Dear all,

I hope this is the correct place to ask this question, if not so, please 
redirect me!

I am trying to produce texinfo documentation for sagemath, a (very large) 
computer algebra system.

The documentation for sagemath is produced by sphinx, which is able to output 
texinfo files.  When browsing the info files with info (in the console) 
everything looks fine.

However, in emacs (24.4.1) all occurrences of "(" followed by a number followed 
by ")", for example

are interpreted as footnote links.  For example, in

AUTHORS:

   - Mike Hansen (2007): Initial version

   - Pierre Cange, Luis Serrano (2012): Added monotone triangles

   - Travis Scrimshaw (2013-28-03): Added element class for ASM’s and
     made *note MonotoneTriangles: 221. inherit from *note
     GelfandTsetlinPatterns: 1fe.


----------------------------------------------------
the (2007) and (2012)  appears underlined and blue.  (2013-28-03) looks OK 
(i.e., black).

The corresponding section in the texi file looks OK:

Travis Scrimshaw (2013-28-03): Added element class for ASM's and made
@ref{221,,MonotoneTriangles} inherit from @ref{1fe,,GelfandTsetlinPatterns}
----------------------------------------------------

I should also mention that several links (for example 
@ref{221,,MonotoneTriangles} above do not go to the correct location.  Again, 
this is only a problem in emacs, not in info.

Help is much appreciated!
