Subject: Rewrite of the next! macro

This patch replaces the next! macro with a next() function. It serves
the same purpose, but instead of only checking for two different
runes (a fallback, or one that matches the peek), it can now take a list
of runes/characters to look ahead for, in addition to the fallback.
