[reboot] Sometimes the delete key does not delete the full item inserted by the keypad

[Victor Thompson]

Using the latest reboot from the store (v2.0.73), sometimes calculations can be entered in a such a way where only part of the item added by the key press remains.

For instance enter the following:
1. "sin" button
2. "(" button
3. Hit delete. Note that only "s" remains on the calculation entry strip

1. "pi" button
2. "(" button
3. Hit delete. Note that only "p" remains on the calculation entry strip

1. "pi" button
2. "e" button
3. Hit delete. Note that only "p" remains on the calculation entry strip

There are probably a number of other combinations that produce similar results.
