Description of problem:
When logrotate is configured to 'delaycompress' and also
to 'mailfirst', it tries to find and send off a file ending
in .gz instead of the still uncompressed file.

Example: we want handle the HTTPD error logs:

/var/log/httpd/error_log {
    daily
    rotate 65
    nomissingok
    ifempty
    olddir /var/log/httpd/error_dir
    create 640 root mpfyrun
    mail techies
    mailfirst
    compress
    delaycompress
    postrotate
        /usr/local/apache2/bin/apachectl graceful
        # there will be some activity on the saved log, so
        # don't compress
        # if you want to compress, sleep for 600 or use delaycompress
        # echo "Rotated httpd error_log"
    endscript
}

When this is run, logrotate gives an error:

sh: /var/log/httpd/error_dir/error_log.1.gz: No such file or directory
Failed to mail /var/log/httpd/error_dir/error_log.1.gz to techies!

How reproducible:
Always

Expected Results:  
The still uncompressed file should be sent out. I expect the actual
code handling 'mailfirst' should not care about whether there is a compressed or
uncompressed file at place 1 in the logfile sequence.
