**Unreleased**
62/76 GNU find features supported.
- Color files with multiple hard links correctly
- At `-O3`, replace command lines with no action with `-false`
- For example, `bfs -true -o -print` becomes `-false`, because `-print` is not reachable
- Move optimizations that rely on the purity of a predicate to `-O2` (the new default)
- Optimize using De Morgan's laws:
- `( ! X -a ! Y ) <==> ! ( X -o Y )`
- `( ! X -o ! Y ) <==> ! ( X -a Y )`
- `! ( X -a ! Y ) <==> ( ! X -o Y )`
- `! ( X -o ! Y ) <==> ( ! X -a Y )`
- `! ( ! X -a Y ) <==> ( X -o ! Y )`
- `! ( ! X -o Y ) <==> ( X -a ! Y )`
- At `-O2`, remove top-level pure expressions
- For example, `bfs -print , -false` becomes `-print`, because the top-level return value is ignored
- At `-O2`, remove negations from the left-hand side of the comma operator
- For example, `-not -print , -print` becomes `-print , -print`, because the return value of the LHS is ignored
- Treat `-`, `)`, and `,` as paths when required to by POSIX
- `)` and `,` are only supported before the expression begins
- Implement `-D opt`
- Implement `-fprint`
- Implement `-fprint0`

- New `make install` and `make uninstall` targets
- Squelch non-positional warnings for `-follow`
- Reduce memory footprint by as much as 64% by closing `DIR*`s earlier
- Speed up `bfs` by ~5% by using a better FD cache eviction policy
- Fix infinite recursion when evaluating `! expr`
- Optimize unused pure expressions (e.g. `-empty -a -false`)
- Optimize double-negation (e.g. `! ! -name foo`)
- Implement `-D stat` and `-D tree`
- Implement `-O`
