shortlog: implement --group=author in terms of --group=<format>

Browse Source 
Instead of handling SHORTLOG_GROUP_AUTHOR separately, reimplement it as
a special case of the new `--group=<format>` mode, where the author mode
is a shorthand for `--group='%aN <%aE>'.

Note that we still need to keep the SHORTLOG_GROUP_AUTHOR enum since it
has a different meaning in `read_from_stdin()`, where it is still used
for a different purpose.
