blogdown 1.16

• Added the command-line option --preserve-tabs to the pandoc_args argument of blogdown::html_page(), so that tabs are preserved by default in code blocks (thanks, @amarakon, #740).

• Fixed a bug that caused config.toml.bak.toml to be recognized as the config file mistakenly, which led to an obscure error (thanks, @CerebralMastication, #742).

• This package requires R >= 3.5.0 now.
