minor bug in procmail 3.22

Hello,

1. I've just found minor bug in procmail.
In case of overquota it's impossible now to get appropriate
message in the log because 'unlink' on my system (RedHat 8.0)
change errno.

Here is the patch, apply it, please, if you find it useful:

+failed:           { int serrno=errno;                      /* save any error information */

+          
           if(linkfolder)
              free(linkfolder);
+         SETerrno(serrno); 
           goto dumpf;
+          }
         }
        strcpy(buf2,buf);
        break;

2. Small question:
Is it possible to put the message 'Quota exceeded while writing ...'
and similar to the stderr only, not to the log ?
I think the procmail logging system, as I understand it, is little inconvenient 
because it doesn't allow to get errors separate of info.
