[BUG] Wrong result when --full-path and .. about fd

[tavianator]

So if --absolute-path is specified, we eagerly normalize the command line search paths:

fd/src/cli.rs

Lines 666 to 672 in 4efc05e

	fn normalize_path(&self, path: &Path) -> PathBuf {
	if self.absolute_path {
	filesystem::absolute_path(path.normalize().unwrap().as_path()).unwrap()
	} else {
	path.to_path_buf()
	}
	}

Without --absolute-path, the search path stays as-is (..). Then later when matching, if --full-path is given, we call path_absolute_form():

fd/src/walk.rs

Lines 513 to 516 in b874462

	let search_str: Cow<OsStr> = if config.search_full_path {
	let path_abs_buf = filesystem::path_absolute_form(entry_path)
	.expect("Retrieving absolute path succeeds");
	Cow::Owned(path_abs_buf.as_os_str().to_os_string())

But path_absolute_form() doesn't normalize:

fd/src/filesystem.rs

Lines 14 to 21 in b874462

	pub fn path_absolute_form(path: &Path) -> io::Result<PathBuf> {
	if path.is_absolute() {
	return Ok(path.to_path_buf());
	}
	let path = path.strip_prefix(".").unwrap_or(path);
	env::current_dir().map(|path_buf| path_buf.join(path))
	}

I think having --absolute-path change the result set is a bug we need to fix. But we need to be careful.

Hmm i suspect the path it is comparing to might be

/tmp/1/2/../foo

@tmccombs That's my guess too. But trying to confirm with --absolute-path causes it to not match any more! I guess that's another bug.
