col: incorrectly reads file argument

[mknos]

• GNU col and OpenBSD col treat the +2 as a bad option; usage string is printed
• This version accepts '+2' as a filename but prints strange output
• I started reading manuals and discovered col is not supposed to accept file arguments
• Only stdin is supposed to be read according to standards document[1]
• The "usage" error for GNU & OpenBSD occurs because remaining arguments are found after getopt is finished

%perl col +2 col # old output
Can't open +2: No such file or directory at col line 71. #!/usr/bin/perl
