I think that svn could use two new revision keywords.

1) N-1, where N is just the other revision argument (left or right).
Personally, I think that PREV should be changed to have this meaning.

2) Last change, let's call this PRIOR. Meaning an item could be changed
in revision 14, 25, and 30. The value of PREV:30 would be 29:30. The
value of PRIOR:30 would be 25:30. Likewise, a value of 30:PRIOR would be
30:25 etc...
