[PATCH] whatchanged: always show the header

If --quiet is passed and there is no patch output, log_tree_commit
will not print the log which is certainly not wanted.

Set the always_show_header option to fix this.

With this, "--quiet" just means the same as "-s" by telling
log_tree_commit to output it. I still haven't completely understood
what the relationship between log_tree_commit, log_tree_diff and
log_tree_diff_flush is but AFAICS sometimes one function shows the log
and sometimes the other one shows it, which I guess has to do with the
QUICK option to diff.

I'm sending this now because it's a one-liner and is probably the
correct behaviour anyway, but a more general solution would be to
convert cmd_log_init to use the option parser and catch --quiet there,
maybe even making it mean the same as -s.
