We all have our lives, no need to apologize.

You need a comma or a @: after "e.g.", to avoid its being interpreted
as the end of a sentence.

I suggest an example of an escape sequence here, ideally from 2 or
more programming languages.

Please use @group..@end group here, since the two parts of this can be
typeset on separate pages, but we don't want each one of thgem to be
broken between pages.

Should this say that they are primarily meant for use with
tree-sitter?

This doc string is too concise to be useful.  Please add some
information from the detailed descriptions above.

It is better to have the parent face font-lock-punctuation-face
defined before it is used.

Thanks.
