// Clean up tokens after emphasis and strikethrough postprocessing:
// merge adjacent text nodes into one and re-calculate all token levels
//
// This is necessary because initially emphasis delimiter markers (*, _, ~)
// are treated as their own separate text tokens. Then emphasis rule either
// leaves them as text (needed to merge with adjacent text) or turns them
// into opening/closing tags (which messes up levels inside).
