`:trac:` links are broken

[ppurka]

Two issues:

1. The use of :trac:`<number>` is broken on the command line. The second link below shouldn't repeat the ticket number of the first one

   sage: integral?
   <removed earlier text>
          TESTS:
   
          A symbolic integral from http://trac.sagemath.org/11445 that was
          incorrect in earlier versions of Maxima:
   
             sage: f = abs(x - 1) + abs(x + 1) - 2*abs(x)
             sage: integrate(f, (x, -Infinity, Infinity))
             2
   
          Another symbolic integral, from http://trac.sagemath.org/11445,
          that used to return zero incorrectly:
   
             sage: f = exp(-x) * sinh(sqrt(x))
             sage: integrate(f, x, 0, Infinity)
             1/2*sqrt(pi)*e^(1/4)
   

2. ​reported upstream. The link in the notebook is actually correct (that is I get the correct ticket number in the second URL), but it should open the documentation in a new tab. Otherwise, there is a huge potential of someone losing all their work just because they forgot to shift-click or something.

#13116 fixed trac tickets in docstrings for command line, but I think it wasn't fixed properly. The problem exists at least as far back as sage-5.1.rc0.

Apply trac_13310-trac.patch​

I think that these are two completely separate issue, and deserve completely separate tickets. In fact, issue 2 is really an issue with the notebook, so should be dealt with ​upstream. I'm attaching a patch for issue 1.

(By the way, I think that the sagenb issue could be fixed by patching the "sphinxify" function, but it should be done at the sagenb github site, not here.)

[ppurka]

This works. Thanks. Issue 2 is ​reported upstream.

[ppurka]

Hmm... the patch does not end with the correct extension, hopefully it is not a problem.

patchbot apply trac_13310-trac.pach

It shouldn't be a problem, but just in case...
