log: convert to parse-options

Browse Source 
Use parse-options in cmd_log_init instead of manually iterating
through them. This makes the code a bit cleaner but more importantly
allows us to catch the "--quiet" option which causes some of the
log-related commands to misbehave as it would otherwise get passed on
to the diff.
