rebase: preserve the 'intermediate-source' attribute of grafts Preserving the 'source' attribute of grafts started with a69a77a80900, which predates the introduction of 'intermediate-source' in 51930a7180bd by a year and a half. It looks like not preserving this was an oversight. On a related note, notice how the source value of 32af76 is no longer visible in the graph above this test. Is it reasonable to import the sha1 translation from evolve.py:relocate() into scmutil or similar, and use that to fixup these attributes as well as the commit message? (I realize that evolve is still experimental, but I don't see a way to do this from the evolve extension.)
