Add the placeholders %ah and %ch to format author date and committer
date, like --date=human does, which provides more humanity date output.

    [GSOC] pretty: provide human date format
    
    Reasons for making this patch: --date=human has no corresponding
    --pretty option.
    
    Although --date=human with --pretty="%(a|c)d" can achieve the same
    effect with --pretty="%(a|c)h", but it can be noticed that most time
    formats implement the corresponding option of --pretty, such as
    --date=iso8601 can be replaced by --pretty=%(a|c)i, so add
    --pretty=%(a|c)h seems to be a very reasonable thing.
    
    Change from v3: Fix format errors.
