docs: // ConvertKVStringsToMapWithNil converts ["key=value"] to {"key":"value"}
  // but set unset keys to nil - meaning the ones with no "=" in them.
  // We use this in cases where we need to distinguish between
  //   FOO=  and FOO
  // where the latter case just means FOO was mentioned but not given a value
