Get wrong tag from gitcl describe with match_pattern in Windows

[zwpaper]

We use vergen-gitcl to get the latest v* tag and build it into binary,
but found it was wrong on Windows, getting the commit sha instead of tags.

we dig into the implementation of vergen-gitcl and found it uses cmd to get the result:

vergen/vergen-gitcl/src/gitcl/mod.rs

Lines 523 to 534 in 367d447

	#[cfg(target_env = "msvc")]
	fn run_cmd(command: &str, path_opt: Option<&PathBuf>) -> Result<Output> {
	let mut cmd = Command::new("cmd");
	if let Some(path) = path_opt {
	_ = cmd.current_dir(path);
	}
	_ = cmd.arg("/c");
	_ = cmd.arg(command);
	_ = cmd.stdout(Stdio::piped());
	_ = cmd.stderr(Stdio::piped());
	Ok(cmd.output()?)
	}

with match_pattern, gitcl will add the --match "v*" as args, notice the quotes within it.

vergen/vergen-gitcl/src/gitcl/mod.rs

Lines 640 to 644 in 367d447

	if let Some(pattern) = self.describe_match_pattern {
	describe_cmd.push_str(" --match \"");
	describe_cmd.push_str(pattern);
	describe_cmd.push('\"');
	}

but as the cmd lib says, all Windows arguments are passed as a single commandline string:

and we did some experiments:

it seems the current implementation can not get the right tag due to the quotes.
