This makes perfect sense now. Thank you for clarifying. Unfortunately, I don't think the patch you provided will help my particular problem. Allow me to elaborate.
As I mentioned before, my project's integration model is to create a separate branch for every change. Specifically, we create a branch from a recent internal tag. So, the model for a simple bug fix looks something like this:
F---G branch1
/ \
D tag1 \ E tag2
/ \ /
A---B C trunk
Revision B on trunk was tagged with tag1. A bug was found in that version, so a branch was created from tag1, a fix was committed to the branch, and then the branch was merged back to trunk. Finally, trunk is tagged with tag2.
The "missing commit" messages show up when git svn fetch is fetching revision C. It warns the there is a cherry-pick from branch1, and states that commits D and F are missing. These commits are just copies, however; there is no code change. The svn:mergeinfo property on trunk also only points at commit G. Should git-svn be ignoring commits D and F, which are copy operations, not code changes?
Also of note is that we very, very rarely cherry-pick commits, and never directly from a branch to trunk. Branches are always integrated back to trunk in their entirety.
