Well, they have scipy mostly written in C++ and davidc as a C developer with a 29000 line commit ;) The code analysis isn't quite perfect and I think there are some bugs in computing the statistics. But it's kind of interesting anyway.

There are bugs, and then there are bugs. It seems like an invariants "numlines >= 0" should pertain even with dodgy language identification. I simply don't know what operations they would do to get negative numbers.
In any case, sloccount tells me that most of scipy *is* C++. The generated sparsetools sources are quite large in addition to all of the Blitz sources.

C++ in scipy mostly is generated code (sparsetools) + blitz. There is also the problem of code reformating: for example, ohloh seems to believe I am an advanced Fortran developer from scipy, whereas I barely know how to code an hello world; I guess this is because of my removal of arpack while the license issue was discussed and solved. IIRC, I did use the svn method to put back the code, so in theory, it should be possible to realize I did not code any of the above.
Also, svn is pretty dumb about renaming (it is just an atomic copy + rm), so if you remove a file, I would not be surprised if you become the author of the whole file for svn in that case. I mean, I am far from being the main author of scipy for any meaningful measure of contribution.
cheers,
David
