Why should we patch a cygwin utility to promote the use of a non-cygwin shell?

Sending text files as application/octet-stream makes them harder to read in 
email.  Consider using a text MIME type instead.

You should fix your mailer to not send duplicate copies of a message when 
writing to a text-only mailing list.

And what's wrong with doing this with what cron already provides:

* * * * * /cygdrive/c/windows/system32/windowspowershell/v1.0/powershell -
Command '"c:\documents and settings\blair sutton\my 
documents\windowspowershell\test\test.ps1" one two three'

I'm not the cron maintainer, but I hope he doesn't bloat the code for this.
