Handle weird cases of token pasting
Especially when token pasting involves floating-point numbers, we can
have some really strange effects from token pasting: for example,
pasting the two tokens "xyzzy" and "1e+10" ends up with *three*
tokens: "xyzzy1e" "+" "10". The easiest way to deal with this is to
explicitly combine the string and then run tokenize() on it.
