wow, if I'm reading the graphs right, 'zstd' long-range matching mode blows 'lrzip' on default settings out of the water in terms of performance

(and that's for the 2017 release, who knows how well it performs nearly 8 years later!)

Random #Gentoo moaning for today:

1. #LibArchive started failing its tests (and #BSDCPIO and #BSDTar started being verbose) because #LRZip decided to repurpose the `-q` option. Previously, it silenced all the verbose output it defaults to, now you actually need to pass `-Q` to silence it.

2. #Git 2.43.2 broke #PkgCheck since `git log` apparently no longer accepts `--no-find-copies`.

`test_extract_tar_lrz` fails due to verbose output from lrzip 0.650+ 路 Issue #2069 路 libarchive/libarchive

When running the test suite with lrzip 0.651 installed, I'm getting the following test failures: 7: test_extract_tar_lrz FAIL 6: test_extract_cpio_lrz FAIL The detailed logs suggest that the proble...

Przypadkowe narzekanie z krainy #Gentoo na dzi艣:

1. Testy w #LibArchive zacz臋艂y si臋 sypa膰 (a #BSDCPIO oraz #BSDTar nagle zacz臋艂y 艣mieci膰 wyj艣cie), bo #LRZip postanowi艂 zmieni膰 przeznaczenie opcji `-q`. Przedtem wy艂膮cza艂a zupe艂nie szczeg贸艂owe informacje na wyj艣ciu, kt贸re LRZip domy艣lnie rzuca, a teraz trzeba podawa膰 `-Q`, 偶eby zupe艂nie wyciszy膰.

2. #Git 2.43.2 zepsu艂 #PkgCheck, bo `git log` przesta艂 akceptowa膰 `--no-find-copies`.
