Add 'human' date format documentation

Display date and time information in a format similar to how people write dates in other contexts. If the year isn't specified then, the reader infers the date is given is in the current year. By not displaying the redundant information, the reader concentrates on the information that is different. The patch reports relative dates based on information inferred from the date on the machine running the git command at the time the command is executed. While the format is more useful to humans by dropping inferred information, there is nothing that makes it actually human. If the 'relative' date format wasn't already implemented then using 'relative' would have been appropriate. Signed-off-by: Stephen P.
