Unless they did something recently to radically break backward compatibility, [^\1\\] means "anything except a control-A or a backslash".

Be sure to read my standard disclaimer if this is a reply.

Update: verified that: 
"\1" =~ /[^\1]/

[download]
fails, while 
"\1X" =~ /[^\1]/

[download]
succeeds in Perl 5.8, validating my original hypothesis at least for the latest public Perl release.
