keep.trailing.zeros not working correctly

[perlmonger]

There is an example of how keep.trailing.zeros is supposed to preform here:
https://github.com/Rapporter/pander/issues/27

The first part of the example stays the same:

> panderOptions('keep.trailing.zeros', F)
>  p(a)
[1] "_7_, _7.1_ and _7.233_"
> panderOptions('keep.trailing.zeros', T)
>  p(a)
[1] "_7.000_, _7.100_ and _7.233_"
> 

But, this example :

> a<-c(7, 7.1, 7.233)
> panderOptions('keep.trailing.zeros', T)
> pandoc.table(a)

does not return the value shown on the page linked above. Instead I get:

- --- -----
7 7.1 7.233
- --- -----

I am also getting a different result for the mtcars example given on the linked page.

> panderOptions('keep.trailing.zeros', T)
> pander(mtcars[1:3, 1:5])

I am on Windows and see this behavior for both R x64 3.2.4 Revised and R x64 3.2.5

Thanks!

I think I'm seeing this bug as well with pander 0.6.0, R. 3.3.1.

I think this was introduced by 9f01b90#diff-06d98d59ee432a4a652caa361f1bfda5L915 (pls check @RomanTsegelskyi if you have some time), and should be fixed with the above commit. Pls let me know if this works or you see any side-effects.
