shell quoting unified

[Roland Illig <roland illig gmx de>]

Hi,

I've written a Perl function shell_quote that works fine with my current 
Perl and a Perl-5.005_003 that I digged out of the depth of the internet.

sub shell_quote
{
	my (@result);
	foreach my $i (@_) {
		my $tmp = $i;
		$tmp =~ s/([^\w\/.+-])/\\$1/g;
		push(@result, $tmp);
	}
	return wantarray ? @result : $result[0];
}

You can use it like this:

sub foofs_copyin
{
	my ($archive, $filename) = shell_quote(@_);
	$filename = shell_quote($filename); # double-quoted
}

The advantage over the current version is the name. It is easier 
readable and it tells the reader our intention.

I'd like it to replace the current regexps.

(Sorry, I'm studying computer science with the special topic "Software 
Development Methodology", so I'm kind of strict concerning these things.)
