[PATCH 0/5] enhance "string_list" code and test

Hi all:

During I study and learn the Git source code, I have found something which could be improved for "string_list".

And this patch mainly enhances the "string_list" code and test.

    1. For code, I mainly fix sign compare warnings.
    2. For test, I move the shell script to clar based unit test.

Thanks, Jialuo
