Fix division by zero without any cols or lines

The URL check uses a division to wrap column indices across lines, which
will cause a runtime error if the size of the terminal is zero columns
wide.

Since a lot of our logic assumes that we at least have one column and
line to work with and our behavior doesn't matter otherwise, this change
fixes the terminal dimensions to have space for at least one cell.
