  1. tail: check_number() too forgiving 

    * Numbers can optionally be given with '-' or '+' prefix
* The number validation function allows numbers with leading garbage (regex match was only on end of string)
* These values were accepted: aaa1 +aaa1 -aaa1
* We can pass a helpful error message to usage() to indicate which argument was rejected
* Style: indent check_number()
* Tested this by passing numbers to -n option
