script extensions

What do we do about ScriptExtensions.txt?

For example, it has:

    # Script_Extensions=Arab Syrc Thaa

    060C          ; Arab Syrc Thaa # Po       ARABIC COMMA
    061B          ; Arab Syrc Thaa # Po       ARABIC SEMICOLON
    061F          ; Arab Syrc Thaa # Po       ARABIC QUESTION MARK

    # Total code points: 3

But it appears to belong to only one script via 

    % unichars --nopager -gbs 'ord == 0x061B'
     ؛  U+061B GC=Po BLK=Arabic                 SC=Common       ARABIC SEMICOLON

And it doesn't test as belonging to the things is say it does here:

    % perl -E 'say chr(0x061b) =~ /\p{Common}/ || 0'
    1
    % perl -E 'say chr(0x061b) =~ /\p{Arab}/ || 0'
    0
    % perl -E 'say chr(0x061b) =~ /\p{Syrc}/ || 0'
    0
    % perl -E 'say chr(0x061b) =~ /\p{Thaa}/ || 0'
    0
