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`)
In particular, we specifically use `long_help` instead of doc comments
because using doc comments will always trim the "." off the end of the
first paragraph, and will include the short help as the first paragraph
of the full help.
