[REQ] Tags With Spaces and Leading Special Characters, e.g., periods `.`

[stephencweiss]

I'd like to see the following rules applied to tags Tag rules:

1. A tag should be opened with #
2. A tag should close at the presence of a new line, another # or a space character -- note, however, that if there's a closing tag, we do not check for the space
3. Any characters can be in a tag (including .)

Additional context Preferably this is applied to both MacOS and iOS.

Would also like case-insensitivity to tags.
