[issue14297] Custom string formatter doesn't work like builtin str.format

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

We know that string.Formatter does not properly duplicate str.format.
#13598 is specifically about use of {}.
Search "string Formatter" for other related issues.
