Summary: glob returns initial argument string, only if no wildcards are
present in the glob argument.  It happens in both scalar and list return
context.

TEST CODE:
use Data::Dumper; use strict;

my $noWildcard = "this_file_does_not_exist";
my $withWildcard = "file_does_not_exist_with_wildcard*";

globtest($noWildcard);
globtest($withWildcard);


sub globtest
{
my $filename = shift;
die if (-f $filename);
print "Testing glob using string '$filename'\n";
my @array = glob($filename);
my $scalarvar = glob($filename);
print Dumper(\@array);
print Dumper(\$scalarvar);
}

OUTPUT:
Testing glob using string 'this_file_does_not_exist'
$VAR1 = [
          'this_file_does_not_exist'
        ];
$VAR1 = \'this_file_does_not_exist';
Testing glob using string 'file_does_not_exist_with_wildcard*'
$VAR1 = [];
$VAR1 = \undef;
