Pressing minus and plus keys followed by a number produces odd results

[Victor Thompson]

To reproduce open calculator app and do the following:
1. Press minus (-)
2. Press plus (+) followed by 6. Note that it allows the calculation to continue with the calculation (see minus-plus-number.png) finishing this calculation will produce -+6 or -6 if the number 6 is hit next.
3. Pres clear (c) twice to reset.
4. Press plus (+)
5. Press minus (-) followed by 6. Note that it shows the calculation to be "+-6" (see plus-minus-number.png)

Expected results: Step #2 should not allow the plus (+) to continue the calculation, it should behave similar to pressing times (x). Step #5 should either replace the plus (+) with a minus (-) when the minus is hit, or preferably, not allow the plus to be used to start a calculation--similar to pressing times (x)

Difficulty: MEDIUM
###### Desidered solution #####
1. Remove the option to add a + after a minus (hint: find the code that prevents to add a * or a / after a minus)
2. Remove the option to add a + as first operator (hint: find the function that prevents to add a * or a / as first operation

This bug still exists for the first two steps (minus followed by plus) in the bug description.

Are you sure? I'm not able to reproduce on rev 213 (code has been merged in rev 212)

Nevermind. I didn't push the Javascript file to the phone.
