Hi Arnaud

Thanks for your work on this -- I see it has now made it onto trunk!
Looking at using it from python, I have a question:

The docstring for clang_CompileCommand_getArg in CXCompilationDatabase.h
says:

> Invariant :
>  - argument 0 is the compiler executable

Whereas the python CompileCommand.arguments says:

> Invariants :
>   - the first argument is the compiler executable
>   - the last argument is the file being compiled

Is that last invariant actually true? If so, does it hold only for the
python, or also the C function? What happens for a command line
compiling and linking multiple source files at once: There would be
multiple entries in the compilation database (one per source file) so
will libclang re-order the command-line entry for each source file so
that the file in question comes last?

Thanks!
