In commit f2729153 (filter-repo: workaround Windows' insistence that cwd
not be a bytestring, 2019-10-19), filter-repo was made to use a special
SubprocessWrapper class instead of the normal subprocess calls, due to
what appears to be in bugs in the python implementation on Windows not
working with arguments being bytestrings. Add the same workarounds to
bfg-ish and filter-lamely.

Partial history rewrites were possible before with the (previously
hidden) --refs flag, but the defaults were wrong. That could be worked
around with the --source or --target flags, but that disabled --no-data
for fast-export and thus slowed things down, and also would require
overridding --replace-refs. And the defaults for --source and --target
may diverge further from what is wanted/needed for partial history
rewrites in the future.
So, add --partial as a first-class supported option with scary
documentation about how it permits mixing new and old history. Make
--refs imply that flag. Make the behavioral similarities (in regards to
which steps are skipped) between --source, --target, and --partial more
clear. Add relevant documentation to round it out.
