This also fixes a couple of problems that are now errors:
- Remove use of unstable-grouped feature flag that no longer exists
- Fix some conflicts rules with non-existant options
* has_results should have been quiet
* count doesn't exist. I'm not sure where it came from
Fixes: #1397
Summary: Currently, `--ignore-vcs` only serves to unset `--no-ignore-vcs`.
There is currently no way to tell fd to respect gitignore files when not in a
git repository. This commit adds the flag `--no-require-git` to make fd always
respect all gitignore files.
This behaves the same as the `--no-require-git` option in [ripgrep](3bb71b0cb8/crates/core/app.rs (L2214-L2226))
This commit also contains an unrelated wording fix to CONTRIBUTING.md
Test Plan: `tests/tests.rs`
Background: I am using [Sapling](https://sapling-scm.com/docs/introduction/)
for working with git repositories (including this commit ☺️). Since Sapling
uses `.sl` instead of `.git`, tools using the `ignore` crate (rg and fd) would show gitignored files.
I made a patch (ebf17eef22)
to `ignore` to respect gitignores with _either_ `.git` or `.sl`. However,
@BurntSushi said he did not want to merge that patch and instead suggested I
use `--no-require-git` (https://github.com/BurntSushi/ripgrep/issues/2374).
This works fine, but I couldn't use this workaround for my other favorite tool!
That's what this patch is for 😁
(a follow-up patch will add a similar `FD_CONFIG_PATH` environment variable
like `RG_CONFIG_PATH`)
