Referring to the pluses themselves? Or I might be misunderstanding? I
was trying to match the format of other records in this file. Many
headings seemed to be followed by a mix of +++ or --- so I thought it
was required? If not I'll just remove it.

Added trailing period.

Is this absolutely necessary? I had thought if the framework for
supporting this was in place then someone could contribute it down the
line but didn't want to prevent a possible terminal feature based on GUI
support (and vice versa). Currently if one tries to set a unsupported
underline style on GUI frames they'll be met with a single underline as
if they didn't specify a style at all. This is the same behaviour we'd
get if a you tried setting a face attribute on terminal frames that's
only supported by GUI frames.

Nice catch. Fixed.

I had thought `M-x tabify` was supposed to normalize this to the Emacs
code standards. Should I manually reindent this to match or is there
another function that can do this for me? Sorry if this is unusual, I'm
accustomed to formatting and linting tools that do this in bulk for me :-).

Fixed and I've looked through a few other places where braces could be remvoed.
