[PATCH 2/2] git-svn.perl: keep processing all commits in parents_exclude

[Steven Walter <stevenrwalter@gmail.com>]

This fixes a bug where git finds the incorrect merge parent.  Consider a
repository with trunk, branch1 of trunk, and branch2 of branch1.
Without this change, git interprets a merge of branch2 into trunk as a
merge of branch1 into trunk.
