Thanks for the quick answers.  It helps.

I think allowing people to clone
https://github.com/zephyrproject-rtos/civetweb but not to check out
the problematic historic revision is a reasonable choice, especially
since it's still possible to get the data from there using

	git checkout <rev> -- . ':!bad-paths'

Every once in a while someone (e.g., in #git) has wanted "git checkout
--skip-index <rev> -- <paths>", and that would be the natural way to
implement such a thing.  But no one has done it yet. :)

We'll just have to keep a watchful eye as people make new
contributions.
