When opening a buffer with `:terminal` trailing whitespace is highlighted in there too. However, this doesn't make much sense. Many programs emit trailing whitespace and highlighting it distracts from their output. Even the user's cursor is considered whitespace so there's always a useless highlight. If the user is interested in trailing outspace in the output of programs for later document formatting, they can apply such text formatting in the document's buffer, where this plugin will be active. Detect terminal buffers and consider them not valid for this plugin. Signed-off-by: Jamie Bainbridge <jamie.bainbridge@gmail.com>
