Prototyped updated tagging functionality.
Fixed a bug in the tag recognition.
Keep handling of remove tag and add tag shorthands separate.
Nice shortcut for tagging the current file, from within Vim.
Warng in case of spaces in the tag indicator.
Strip line breaks from added tags, so that the tagline stays one
line.
Strip all line breaks, even in the middle of tags. We really want the tags to stay on one line.
Consider multiple lines all starting with :tags:
Ensure that the :tags: indicator is always at the start of the line.
