cron without sendmail generates bogus logfile names

[Linus Hicks]

The "poor man's mailer" included as part of the cron package uses the
following construct to generate part of the filename used in making
log file names:

DATE=$(date '+%Y%m%d_%H%M%S')

It then generates the filename as:

FILE="/tmp/cron.$DATE.$$.log"

However, it seems to be tacking on a CR character at the end of the
DATE portion which messes up the generated filenames. I cannot
reproduce this behavior in sh running in an xterm window:

oracle@ERPPRODDBS03 log $ DATE=$(date '+%Y%m%d_%H%M%S')
oracle@ERPPRODDBS03 log $ echo $DATE
20080909_170639
oracle@ERPPRODDBS03 log $ FILE="/tmp/cron.$DATE.$$.log"
oracle@ERPPRODDBS03 log $ echo $FILE
/tmp/cron.20080909_170639.6588.log
oracle@ERPPRODDBS03 log $ ls -l /usr/sbin/sendmail
lrwxrwxrwx 1 oracle None 16 Jul  3 15:00 /usr/sbin/sendmail -> /usr/bin/cronlog*
oracle@ERPPRODDBS03 log $

Here's a hexdump of the cron.log showing the spurious characters:

oracle@ERPPRODDBS03 log $ hexdump.exe -C cron.log

I am baffled as to why this is a problem, and have seen it on two
different systems both running Windows 2003 Server.
