Git supports it "pretty well" because its merge algorithms are pretty
smart (I've never had a problem in practice), but it can't do as well
as SVN does for the particular use case Volodya has mentioned.

For everyone's reference, here's where he ended up:

  Commits in HEAD
  4faabacc * master Do something after cherry-pick
  0468cdd0 * C2
  f5b6b987 | * feature C3
  fb0de3f5 | * C2
  7c8f9509 | * C1
           |/  
  04e628f9 * Initial version

The last commit on master changed lines that were also changed by C2.
Because 0468cdd0 and fb0de3f5 (the two C2's) are separate commits, Git
has no way to recognize that fb0de3f5 has been incorporated into
4faabacc, so it will try to make those changes again when "feature" is
merged into "master."
