Yes - first it determines from which version on the old master it was 
branched off, finds the corresponding commit in the new master, and 
rebases it onto that one (since historical branches might not apply 
cleanly to the latest master). It also accomplishes it using

you can comment out a few lines to make it use rebase instead of
