[OS X TeX] How does Texhshop count words?

[Themis Matsoukas]

I used Edit/ Statistics… to count words in my source file. With the entire file selected (from first line to last, comments and all), I get a word count of 3045/20021 characters. If I select from my \begin{abstract} to the end of the file, I get 3381 words/22663 characters! I didn’t expect the count to be exact but I would have thought that a subset of the document would give a lower count that the whole. With some experimentation I discovered that when  the line \begin{document} is excluded,  the count increases by ~300 words. That’s with a revtex document, I am not sure if the same is seen with other classes. 

Not a big deal but since Dick is a mathematician I thought he’d want to know that there is a discontinuity that breaks monotonicity in the count :)
