Comment (by steven_watanabe):
Your patch prevents BOOST_PP_SEQ_REST_N from handling empty sequences. In
the current C++ standard, empty sequences don't work because empty macro
arguments are illegal, but IIRC, C99 and C++0x both allow empty macro
arguments.
See http://chaos-pp.cvs.sourceforge.net/viewvc/chaos-pp/chaos-
pp/chaos/preprocessor/seq/drop.h?hideattic=0&revision=1.3&view=markup for
another implementation.
