After having looked into clang_complete (thanks for the tip, Tobias!) I
came to the conclusion that I'd coded my code completion logic wrong. I
was under the impression that before invoking clang_codeCompleteAt one
had to reparse the TU but it turns out that's not the case - all one has
to do is feed the source file contents in a CXUnsavedFile struct.

Thanks for your invaluable help!
