Sergei Trofimovich a649d4f038 python: use whitespace to split possible existing options
Noticed option globbing when tried to enable parallelism by default
locally for most packages by default. python3Packages.yt-dlp failed as:

    python3.9-yt-dlp> /nix/store/5mywvxdjkk1q6srwwwgdkzc37ibla801-python3.9-setuptools-61.2.0/lib/python3.9/site-packages/setuptools/dist.py:516: UserWarning: Normalizing '2022.04.08' to '2022.4.8'
    python3.9-yt-dlp>   warnings.warn(tmpl.format(**locals()))
    python3.9-yt-dlp> invalid command name 'build_lazy_extractors--parallel'

The change adds leading whitespace everywhere where options might
already be present.
