Suggestion of clarification in the language reference documentation

[RebelusQuo]

Please excuse me for posting this as an issue rather than a PR, but I find it hard to motivate a fork just for minor changes to the documentation.

As I read through the document the Line-type tags section had me imagine a "tag" as a single character due to all the examples being one character. Later sections do more directly speak of them as a character followed by space or line break, but I would like to suggest the following for clarifications:

Under the Line-type tags section, change the numbered list:

1. the first of these specific characters when followed immediately by a space or line break: dash (-␣, -↵), colon (:␣, :↵), or greater-than symbol (>␣, >↵), or
2. the first non-white space character on a line being one of a hash (#), left bracket ([), or left brace ({).

Replace each occurrence of the phrase (for some <char>):

by a space (<char>␣) or a line break

With:

by a space or a line break (<char>␣, <char>↵)

I think I understand. Let me work on that section to try to be more clear and consistent about what I mean by a tag.

Okay, I have updated the documentation in GitHub with the clarifications.
