BOOST-PP_TUPLE-REM-CTOR and BOOST-PP-REOVE-PARENS behave incorrectly on the msvc compiler

BOOST_PP_TUPLE_REM_CTOR((x, y, z)) // expands to x,But the document says it will expand into x, y, z
BOOST_PP_REMOVE_PARENS((a, b, c)) //expands to a,But I think it will unfold into a, b, c

Start by reproducing the two macro expansions in the issue body with the MSVC compiler and compare them with the documented expansions. Inspect the implementation and documentation for BOOST_PP_TUPLE_REM_CTOR and BOOST_PP_REMOVE_PARENS, then confirm that both expand to all three comma-separated values as documented.
