[New-bugs-announce] [issue44146] Format string fill not handling brace char

[svs]

New submission from svs <snegavs at outlook.com>:

Format strings and f-strings don't seem to handle brace characters as a fill character.

E.g.

'{::>10d'.format(5) => ':::::::::5"  (as expected)

'{:{>10d'.format(5) => error. Expect: '{{{{{{{{{5"

trying {{ escape does not work either.
'{:{{>10d'.format(5) => error.

The same goes for '}'. f-strings have a similar issue.
