RFR: 5035569: assertion error in Formatter

The assertion is due to a condition occurring which is contrary to the specification. The specification is accurate but insufficiently forthcoming that the %a conversion is unsupported for BigDecimal. This change clarifies the situation by updating the conversion table which occurs earlier in the class comments.
