	Important tasks start with a `!` instead of a `-`. Highlight them separately from normal tasks so that they can be visually distinguished. Here we use the Error highlight group for them because it's red (at least in my colour scheme).
2016-04-05	syntax/todo.vim: Highlight TODOs that start with whitespace	Teddy Wing
	Subtasks get indented. This will highlight undone tasks even if there's whitespace in front of them.
2016-04-05	syntax/todo.vim: Remove old highlight code	Teddy Wing
	These lines were copied from my manual highlighting of TODO files created a few days ago. They served as a guide while creating the highlighting in the syntax file.
2016-04-05	Add syntax file	Teddy Wing
	Based on Ch. 45 of Learn Vimscript the Hard Way (http://learnvimscriptthehardway.stevelosh.com/chapters/45.html). Highlights undone TODOs as Vim `Statement`s.
