you meant,

 hg log -r tip -p --stat == hg log -r tip -stat

thats the current behavior.

thats because diffordiffstat(stat) does something like this:

    if stat:
        print stat
    else:
        print diff

So the 'stat' option always suppresses 'show patch' option.

It indeed is.  The patch above fixes this.  The patch mainly changes
diffordiffstat(stat) to something like stat_and_or_diff(stat, diff).
Alternatively, we can keep diffordiffstat() untouched, but instead
change the caller path to something like this:

    if stat:
       call diffordiffstat(stat = True)
    if diff:
       call diffordiffstat(stat = False)

We can wrap out some helper to do this anyway.  But i personally prefer
the first way.  What say you?

And Yuya?

Since hg diff is meant to show diff (duh), adding a default show-diff
option (-u) makes sense.  In a way, it's quite like what hg blame does
for default option (-n).
