Yann Collet 51da2d2ff2 improved compression of literals in specific corner cases ...

In rare cases, the default huffman depth selector is a bit too harsh,
requiring brutal adaptations to the tree,
resulting is some loss of compression ratio.
This new heuristic avoids the worse cases, favoring compression ratio.

As an example, compression of a specific distribution of 771 literals
is now improved to 441 bytes, from 601 bytes before.
