[issue12014] str.format parses replacement field incorrectly

[Ben Wolfson]

My last examples were actually just attempting to figure out what triggered the unexpected behavior. I don't want to do expansion inside the field_name part!

(I'll have a reply to your previous comment about use-cases shortly.)
