bug: git failure when branch and filename collide

Start at bin/release.js lines 316-323 and inspect the Git log invocation shown in the report. Reproduce the failure with a branch and file or directory sharing the same name, then verify the release command completes without Git's ambiguous-argument error.

I assume this is related to #186

When you have a file/directory with the same name as the branch you get an error.
