One possible fix is below. It adds back the `len == max_len` check and
verifies that the Huffman tree is complete. A complete Huffman tree cannot
contain unused prefixes, so this eliminates the code out of bounds check.

${var:+value} and ${var+value} differ in how they handle the case when
var="" (i.e. defined, and assigned the empty string).
In this case, the check verifies that LESSMETACHARS is set (even if it's
set to the empty string), so it seems correct as is.
