bdcd5c2c0a Handle escaped braces in f-strings 
To use a curly brace in an f-string, you must escape it. For example:

  >>> k = 1
  >>> f'{{{k}'
  '{1'

Saving this as a script and running the 'tokenize' module highlights
something odd around the counting of tokens:

  ❯ python -m tokenize wow.py
  0,0-0,0:            ENCODING       'utf-8'
  1,0-1,1:            NAME           'k'
  1,2-1,3:            OP             '='
  1,4-1,5:            NUMBER         '1'
  1,5-1,6:            NEWLINE        '\n'
  2,0-2,2:            FSTRING_START  "f'"
  2,2-2,3:            FSTRING_MIDDLE '{'     # <-- here...
  2,4-2,5:            OP             '{'     # <-- and here
  2,5-2,6:            NAME           'k'
  2,6-2,7:            OP             '}'
  2,7-2,8:            FSTRING_END    "'"
  2,8-2,9:            NEWLINE        '\n'
  3,0-3,0:            ENDMARKER      ''

The FSTRING_MIDDLE character we have is the escaped/post-parse single
curly brace rather than the raw double curly brace, however, while our
end index of this token accounts for the parsed form, the start index of
the next token does not (put another way, it jumps from 3 -> 4). This
triggers some existing, unrelated code that we need to bypass. Do just
that.

fce93b952a prevent duplicate plugin discovery on misconfigured pythons 
for example, `venv`-virtualenvs on fedora have both `lib` and `lib64` on
`sys.path` despite them being the same.  this causes
`importlib.metadata.distributions` to double-discover.

```console
$ docker run --rm -t fedora:latest bash -c 'dnf install -qq -y python3 >& /dev/null && python3 -m venv venv && venv/bin/pip -qq install cfgv && venv/bin/python - <<< "from importlib.metadata import distributions; print(len([d for d in distributions() if d.name == '"'"'cfgv'"'"']))"'
