ANN: pandoc 2.17.1.1

[John MacFarlane]

I'm pleased to announce the release of pandoc 2.17.1.1,
available in the usual places:

Binary packages & changelog:
https://github.com/jgm/pandoc/releases/tag/2.17.1.1

Source & API documentation:
http://hackage.haskell.org/package/pandoc-2.17.1.1

Mainly this release just fixes a bad regression in 2.17.1,
which broke the expected behavior of `--defaults` (defaults
files were no longer found in the default user data directory).
