Option to overwrite files supplied by -o & -e

[hepcat72]

I just noticed that when you use -o and -e to set the standard output file names, those files are open in append mode.

If it's not already a part of versions past my version of 8.1.3, I'd like to request an enhancement: please provide an option to overwrite any existing standard out and standard error files supplied with -o or -e.

The reason for this is that I assess whether a job had any problems by grepping for errors. If there's an error, I resubmit each job that had an error. However, since the files are open in append mode, those errors remain in the file.

Thanks,
Rob
