Hex strings allow a string postfix like any other string literal, but 'w' and 'd' can't create array elements larger than 255, they just pad each byte from the hex string with 1 or 3 zeros.
```
string a = x"11 22 33 44"c;
wstring b = x"1122 3344"w; // equal to [0x0011, 0x0022, 0x0033, 0x0044]
dstring c = x"11223344"d;
pragma(msg, a.length); // 4
pragma(msg, b.length); // 4
pragma(msg, c.length); // 4
```
It would be more sensible to make the wstring equal to [0x1122, 0x3344] and the dstring [0x11223344], or to disallow a postfix on a hex string.
In any case, the spec should document the behavior.
