-
-  The concept of a 'module' here is a as follows:

-  same 'module' if they are in the same directory.
-  some/path/public/xyzzy and some/path/internal/xyzzy are also considered
-  to belong to the same module here.
-
-  If the filename_cc contains a longer path than the filename_h, for example,
-  '/absolute/path/to/base/sysinfo.cc', and this file would include
-  'base/sysinfo.h', this function also produces the prefix needed to open the
-  header. This is used by the caller of this function to more robustly open the
-  header file. We don't have access to the real include paths in this context,
-  so we need this guesswork here.

-  according to this implementation. Because of this, this function gives
-  some false positives. This should be sufficiently rare in practice.
