rebase!

[Neal Becker]

I  had my first chance to try out rebase, and it went well.  I have a tree of boost_1_36_0 and one with a few of my own patches.  Yesterday I did:

cp -al boost_1_36_0 boost_1_37_0
tar xjf ~/boost_1_37_0.tar.bz2 
cd boost_1_37_0
hg addremove
hg ci -m 'update to 1.37.0'
cd ..
cp -al boost_1_36_0.hg boost_1_37_0.hg
cd boost_1_37_0.hg
hg pull --rebase ../boost_1_37_0

Worked fine.  Only minor issue is that when viewing 'summary' using hg serve, the dates of patches are out of order - but I suppose this can't be avoided.
