Auto-generated .gitignore lost with trunk deletion/recreation.
The attached SVN dump results in an auto-generated .gitignore being added in the first git revision (correct), but that deleted in the "Re-add trunk." revision (wrong). Recreating a branch with a copy (without changing svn:ignore in the process) should preserve any auto-generated .gitignore file. Tested with: reposurgeon "read <test.svn" "sourcetype svn" "prefer git" "rebuild test-git"
