EraseInLine calls `FillConsoleOutputCharacterW()`. In filling the row with
chars, we were setting the wrap flag. We need to specifically not do this on
ANY _FILL_ operation. Now a fill operation UNSETS the wrap flag if we fill to
the end of the line.
Originally, we had a boolean `setWrap` that would mean...
- **true**: if writing to the end of the row, SET the wrap value to true
- **false**: if writing to the end of the row, DON'T CHANGE the wrap value
Now we're making this bool a std::optional to allow for a ternary state. This
allows for us to handle the following cases completely. Refer to the table
below:
,- current wrap value
| ,- are we filling the last cell in the row?
| | ,- new wrap value
| | | ,- comments
|-- |-- |-- |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 0 | 1 | 1 | THIS CASE WAS HANDLED CORRECTLY
| 1 | 0 | 0 | THIS CASE WAS UNHANDLED
| 1 | 0 | 1 |
| 1 | 1 | 1 |
To handle that special case (1-0-0), we need to UNSET the wrap. So now, we have
~setWrap~ `wrap` mean the following:
- **true**: if writing to the end of the row, SET the wrap value to TRUE
- **false**: if writing to the end of the row, SET the wrap value to FALSE
- **nullopt**: leave the wrap value as it is
