Be more conservative about avoiding lexing conflicts when merging states
...
This fixes a bug in the C++ grammar where the `>>` token was merged into
a state where it was previously not valid, but the `>` token *was*
valid. This caused nested templates like -
std::vector<std::pair<int, int>>
to not parse correctly.

'Test' is a lot more straightforward of a name.
