> If one accidentally confuses the long and short argument name styles, then the value of the argument is 
> incorrect. This is mad clear by an example:
> If I have a program that I call as follows:
> my_prog --file my_file.txt
> or
> my_prog -f my_file.txt
> but I make a typo and write
> my_prog -file my_file.txt
> then getOptionValue('f') will return "ile" (i.e. it thinks the remainder of the argument's name is the 
> argument). "my_file.txt" will be ignored.
> This is clearly an error that the user has made, but I think that CLI should be able to detect such an 
> error and throw an appropriate exception.
