[PATCH] Fix build errors in bindings with SWIG 3.0.4

Hello,

I saw build errors in the bindings with SWIG 3.0.4:
./subversion/bindings/swig/core.i:792: Error: Unknown SWIG preprocessor
directive: The (if this is a block of target language code, delimit it
with %{ and %})

The attached patch fixes the comment style issue in trunk and 1.8.x.
