Summary: curl accepts illegal symbols in the date input by "-z"

Initial Comment:
In curl-7.16.0,7.16.1 and latest snapshot source code, when user executes a command as the following:

$ curl -v www.google.com -z "dec 12 11:00:00 $$%% GMT"

It will "correctly" display the following:

* About to connect() to www.google.com port 80 (#0)
* Trying 64.233.189.104... connected
* Connected to www.google.com (64.233.189.104) port 80 (#0)

I think curl should check the input date format and not accept the illegal/meaningless symbol like "$$%%". The input is invalid and curl gives a valid "If-Modified-Since" value. Is it a bug or a design as-is?

This problem can be reproduced on multiple Linux and Unix platforms. I think it is a generic problem.

Please feel free to let me know your ideas.

Thanks

While possibly a problem, I consider it very minor and I'm personally not
planning on working on fixing this anytime soon. Are you?
