When at the last position of the document, the scope becomes that of  
the character to the left of the caret (since there is nothing to the  
right).

What you can do is detect this case and use a slightly different  
pattern.

For example something like this rule:

    {  name = 'meta.end-of-file';
       match = '.(?!\n)$';
    },

Will make the caret, when at the end of the file, give a scope of  
`meta.end-of-file`, although since it actually assigns the scope name  
to the character to the left of the caret, there a) needs to be such  
character (so if the last line is empty, it won’t work), and b) the  
second-last position in the document will also get this scope name.
