String::ShellQuote - quote strings for passing through the shell

       Roderick Schertler <roderick@argon.org>

       Only Bourne shell quoting is supported.  I'd like to add other shells (particularly cmd.exe), but I'm not
       familiar with them.  It would be a big help if somebody supplied the details.

       This module contains some functions which are useful for quoting strings which are going to pass through
       the shell or a shell-like object.

       shell_quote [string]...
           shell_quote  quotes  strings  so they can be passed through the shell.  Each string is quoted so that
           the shell will pass it along as a single argument and without further interpretation.  If no  strings
           are given an empty string is returned.

           If any string can't be safely quoted shell_quote will croak.

       shell_quote_best_effort [string]...
           This  is  like  shell_quote,  excpet if the string can't be safely quoted it does the best it can and
           returns the result, instead of dying.

       shell_comment_quote [string]
           shell_comment_quote quotes the string so that it can safely be included in a shell-style comment (the
           current algorithm is that a sharp character is placed after any newlines in the string).

           This routine might be changed to accept multiple string arguments in the future.  I haven't done this
           yet because I'm not sure if the strings should be joined with blanks ($") or nothing ($,).  Cast your
           vote today!  Be sure to justify your answer.

           $cmd = 'fuser 2>/dev/null ' . shell_quote @files;
           @pids = split ' ', `$cmd`;

           print CFG "# Configured by: ",
                       shell_comment_quote($ENV{LOGNAME}), "\n";
