Problem or Use Case

Compression preserves a head that's currently set to protect_first_n=3, hard-coded. I would like to not have compression preserve the first turn.

Proposed Solution

A protect_last_n already is exposed to config, so I figured the easiest path forward would be to expose a parallel config variable.

Alternatives Considered

Could just hard-code it in my fork, but might as well upstream the change.

Feature Type

Configuration option

Scope

Small (single file, < 50 lines)
