Shared Logic between Command Mode and Search Mode

Command and Search use very similar logic for parsing user input. The logic functions like this:

Command/Search mode is entered
Go to bottom line, clear and add mode character : / /
With each character typed, print the char to the screen and to a buffer
When the user pressed enter, either hand off the input to another function or var

I believe that this logic should be it's own function like so:

int parseUserInput(char *bufferToWriteTo) {
    // parse input
    // write to supplied buffer (if needed)
    // return 0 (fail) 1 (success)
}

This will allow code reuse, and any function that uses user input in the future will benefit from this function.
