[PATCH 2/3] Add 'human' date format documentation

["Stephen P. Smith" <ischis2@cox.net>]

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.

+`--date=human` shows the timezone if it matches the current time-zone,

+year for dates that are "this year", but also skip the whole date

 `--date=unix` shows the date as a Unix epoch timestamp (seconds since
 1970).  As with `--raw`, this is always in UTC and therefore `-local`
 has no effect.
