Interactive options in sqlexport should accept uppercase Y or N.

Compare with Bash ( man a and hit tab and then when terminal shows Display all possibilities? (y or n) enter Y will show all commands with a)

-i, --interactive
Prompt before overwriting DESTINATION if it exists and is not a folder.

For e.g

/home/tariq/User Files$:1> sqlexport -i -f csv -d world country  -o /home/tariq -de                                                                                                       
sqlexport: The file '/home/tariq/export.txt' exists. Do you want to overwrite it? (y or n) Y            

Entering Y terminates the sqlexport, which should not be the case
