dcommit will still rewrite the HEAD commit and the history of the first parents of each HEAD~1, HEAD~2, HEAD~3 as it always has. However, any merge parents (HEAD^2, HEAD^^2, HEAD~2^2) will now be preserved when the new HEAD and HEAD~[0-9]+ commits are rewritten to SVN with dcommit. Commits written to SVN will still not have any merge information besides anything in the commit message. Thanks to Joakim Tjernlund, Junio C Hamano and Steven Grimm for explanations, feedback, examples and test case.
