Set console window size

The program has an algorithm setting the size of the console window so it won't be bigger than necessary, This prevents line-breaks due to small width. However, changing the window size can be annoying if one is running the program from the Windows command prompt.

- [ ] Change the algorithm so it won't shrink the window. Only increases of the size should be done.
- [ ] Store the current size and reset it when the program is done.

Locate the algorithm that changes the console window size and inspect how the program finishes. Make the sizing behavior increase-only, preserve the original size, and restore it on exit; verify both behaviors from the Windows command prompt.
