curl respects the locale's number format setting for parsing fractional seconds, it does not enforce dot #9969
Description
I did this
In bash and zsh: curl --connect-timeout 3.14 https://example.com
I expected the following
The following printed out to stdout:
<!doctype html>
<html>
<head>
<title>Example Domain</title>
...
</html>
The actual result was
curl: option --connect-timeout: expected a proper numerical parameter
