[PATCH 5/6] log: pass rev_info to git_log_config()

[Junio C Hamano <gitster@pobox.com>]

Call init_revisions() first to prepare the revision traversal
parameters and pass it to git_log_config(), so that necessary bits
in the traversal parameters can be tweaked before we call the
command line parsing infrastructure setup_revisions() from
the cmd_log_init_finish() function.

 * This is made separate from the next one that touches the contents
   of "rev" to make sure the existing code does not depend on the
   current initialization order.  I do not think it does but better
   be careful to keep the history easier to bisect, than be sorry
   when an issue does appear.
