[PATCH v2] remote: align --verbose output with spaces

["Wang Bing-hua via GitGitGadget" <gitgitgadget@gmail.com>]

From: Wang Bing-hua <louiswpf@gmail.com>

Remote names exceeding a tab width could cause misalignment.
Align --verbose output with spaces instead of a tab.

    remote: align --verbose output with spaces
    
    Changes in v2:
    
     * Use for_each_string_list_item() to traverse string lists.
     * Calculate the max width outside of the loop.
