Suspicious duplicate condition in java.util.regex.Grapheme#isExcludedSpacingMark

[Andrey Turbanov]

Hello.
I found suspicious condition in the method
java.util.regex.Grapheme#isExcludedSpacingMark
It's detected by IntelliJ IDEA inspection 'Condition is covered by
further condition'
https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/util/regex/Grapheme.java#L157

```
private static boolean isExcludedSpacingMark(int cp) {
   return  cp == 0x102B || cp == 0x102C || cp == 0x1038 ||
           cp >= 0x1062 && cp <= 0x1064 ||
           cp >= 0x1062 && cp <= 0x106D ||  // <== here is the warning
           cp == 0x1083 ||
           cp >= 0x1087 && cp <= 0x108C ||
           cp == 0x108F ||
           cp >= 0x109A && cp <= 0x109C ||
           cp == 0x1A61 || cp == 0x1A63 || cp == 0x1A64 ||
           cp == 0xAA7B || cp == 0xAA7D;
}
```
There are 2 sub-conditions in this complex condition:
cp >= 0x1062 && cp <= 0x1064 ||
cp >= 0x1062 && cp <= 0x106D ||

The second condition is _wider_ than the first one.
I believe it's a bug. The second condition (according to
https://www.compart.com/en/unicode/category/Mc) should look like this:

cp >= 0x1067 && cp <= 0x106D ||

0x1065, 0x1066 are not from the Spacing_Mark category.
