- count of params is available as $#, we don't need the pipe-to-wc logic.
- the whole 'CONTINUE' based logic is silly, we can just return once one
of the files is found.
- setting of 'NAME' in the loop was completely pointless.
- the error message for multiple files was not very clear just injecting
a sequence of words into a sentence.
- it did not work correctly if no arguments were given (bad usage)
note, you might question whether the functionality of this function is
correct, as did I; this is tackled in a followup commit whilst this
commit retains the existing functionality!
