Implementation of the wc UNIX command line tool in Go.
The wc utility displays the number of lines, words, and bytes contained in
each input file, or standard input (if no file is specified) to the standard
output. A line is defined as a string of characters delimited by a ⟨newline⟩
character. Characters beyond the final ⟨newline⟩ character will not be included
in the line count.
