Added missing null terminator when adding characters to the string, otherwise garbage values are read (often zeros which are equal to '\0', but not every time).

This error results in random characters appearing in the text box every one in a while:
```
asdfg??? ll??
```
It is corrected with the proposed fix.

This problem was observed by my student, Gonzalo Rivera Lazo.
