screen: Adjust buffer sizes for multiple sign columns #10314
* screen: Fix to draw signs with combining characters.
The buffer size for signs can be too small, because the upper length
limit of a sign can be 56 bytes. If combining characters are only two
bytes in size, this reduces to 32 bytes.
* screen: Adjust buffer size to maximal sign column count
