R CITATION file: get rid of comma after last entry?

I am an R package author and have written a CITATION file for inclusion in the package. However, a comma is usually added to the BibTeX output of CITATION entries when I display them using the citation command in R. This is not correct according to the BibTeX specifications. How can I suppress or get rid of this comma -- if possible, already when I write my CITATION file? Why is the comma there in the first place?

I noticed that even the base and the stats package have this comma. Here is an example of the output of citation("base"):

@Manual{,
  title = {R: A Language and Environment for Statistical Computing},
  author = {{R Core Team}},
  organization = {R Foundation for Statistical Computing},
  address = {Vienna, Austria},
  year = {2014},
  url = {http://www.R-project.org/},
}

Note the comma after the url entry and before the last curly brace.

You are wrong to say "This is not correct according to the BibTeX specifications". The BibTeX Format Specification at http://www.bibtex.org/Format/ specifically says

The last tag can be finished with a comma, although not necessarily.

@article{mrx05, 
auTHor = "Mr. X", 
Title = {Something Great}, 
publisher = "nob" # "ody", 
YEAR = 2005, 
}

is a correct BibTeX entry.
