It's good as is.  The mini language used in doc.str is implemented in
makedoc.c.  The language has a 'dup' intrinsic which is mapped to the
C function 'dup_' on line 1413 by:
     add_intrinsic("dup", dup_ );

so the function name change doesn't affect the keyword.

Tested by building lib{c,m}/lib{c,m}.info with and without the patch.
The generated files are identical.
