Hello brothers,

I've stumbled across the following code: 

  my $mask    = shift;
  my @folders    = glob("$mask");

  if (scalar(@folders) == 0) {
    return undef;
  }

It seems unelegant and unrobust to me, so I investigated a little bit further. To my surprise I found a strange behaviour of glob, when a glob is given that does not match but that does not contain wildcards also. Given the folowing examples: 
@t1 = glob('*1');
@t2 = glob('1');
@t3 = glob('file2');
@t4 = glob('*3');

assume you have the files file1 and file2 in the directory glob is searching, the returns are 'file1' for @t1, '1' for @t2, 'file2' for @t3 and the empty list for @t4.

The behaviour for @t2 is what seems odd/annoying. In my opinion it should be empty, as the current semantics make it indistinguishable from the @t3 case - which is correct imho.

Please tell me, that I've found a bug that is soon to be fixed... :-}

Bye
