Another patch from Olly Betts:

Rename uses of variables called "c" in the generated code.  In the C++ backend
for Xapian, "struct SN_env" is used as the base class, so these would shadow
the base class member "c" (i.e. "z->c" in the C code).  Renaming to "ret" also
improves the clarity of the generated code.

Also, combine "int ret;" followed by "ret =" into a single statement, and
eliminate an inner block in one case.
