When are COMBINING DOUBLE things lb=CM vs. GL?

https://util.unicode.org/UnicodeJsps/list-unicodeset.jsp?a=%5B%3AName%3D%2FCOMBINING+DOUBLE%2F%3A%5D&g=lb&i=

When they span two base characters, they are GL. When they just go over one base character, they are CM. The naming intersection is a little unfortunate.

Ok, and looking at L2/24-232 the two new double accents below go under just one base character. Thanks!

Should we add the NamesList.txt annotations that L2/24-232 proposes? Or leave those to @Ken-Whistler ?

1AF0 COMBINING DOUBLE COMMA ABOVE
→ 0313 COMBINING COMMA ABOVE
→ 02EE MODIFIER LETTER DOUBLE APOSTROPHE

We leave the names list to @Ken-Whistler.
