[Rd] [PATCH] Three improvements to confint() documentation and S4 support

[Ben Bolker]

   Sorry for my confusion. I've now looked at the patches (which are 
here -- they were originally proposed as pull requests in Winston 
Chang's Github mirror of the R SVN source tree:

https://github.com/wch/r-source/pull/22/changes/589eeaf9aa53cb4a5fbfc751e95e4706f2b26f37

)

  Looking at the NEWS file it doesn't seem that news entries typically 
have examples.  It might be more useful to add these examples to the 
appropriate Rd files.  For example, it doesn't look like any examples 
were added to src/library/base/man/substr.Rd when this change was committed:

https://github.com/wch/r-source/commit/761fbd17655e918210610adaf057858910ca2b2f

    As I mention here https://stackoverflow.com/a/8066062/190277 , 
R-core tend to be very conservative about accepting patches to the code. 
Take a look at https://contributor.r-project.org/ for some of the 
supports for getting started with contributions to the R code base ...

   cheers
    Ben Bolker
