If a zero value appears in a SinglePos statement, feaLib continues to produce ValueRecords of format 0. But if a zero value appears in a PairPos statement inside a horizontal compilation context, feaLib now produces ValueRecords of format 4. Likewise, if a zero value appears in a PairPos statement inside a vertical compilation context, feaLib now produces ValueRecords of format 8. The OpenType Feature Syntax specification is completely silent about this, but the new behavior matches that of makeotf. https://github.com/fonttools/fonttools/issues/633
