Elijah Newren dab9386c47 contrib: update bfg-ish and filter-lamely with windows workaround
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.

Elijah Newren 0590c4193d contrib: clarify a few points of usage
Make it clearer that absolute paths should not be used for pathnames
within a git repository.  Also, fix the comment about how the
insert-beginning script could be implemented as a one-liner; the
example commented-out code should have used bytestrings.

Elijah Newren 320c85f941 filter-repo: improve support for partial history rewrites
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.

Elijah Newren df575fb181 contrib: new filter-repo demo named filter-lamely (or filter-branch-ish)
This is a re-implementation of git-filter-branch that is nearly
perfectly bug compatible (it can replace git-filter-branch and still
pass the git testsuite).  It deviates in one minor way that should not
matter to real world usecases, but allows it to run a few times faster
than filter-branch.
