[TxMt] tiny improvements for perlmate.rb

[Hans-Joerg Bibiko]

Now I'm able to distinguish separately:

-syntax errors (missing colons etc.)
   via $SIG{__DIE__} = \&syserror;
-system errors
   via $SIG{__DIE__} = \&syserror;
-system warnings (useless use of etc.)
   via $SIG{__WARN__} = \&syswarn;
-user-defined warnings (warn("foo";)
   via ::warn
-die statements
   if it occurs within eval block
        message will printed out and the program runs further
   else
        message will printed out and the program will be aborted due  
to exception

In order to hide stderr for perlmate you have to write in perlmate.rb

class PerlMate < ScriptMate
   def filter_stderr(str)
     ""
   end
end



I don't use your 'sub id' except for 'sub warn'. Here everything  
should be clear. Otherwise I trust Perl's error messages more than  
'caller($level);'. Esp. for the case if Perl's message contains more  
than one link like Carp::longmess() it often does.

Comments?


This code is up to now very redundant. It's only for testing!
