BUG:	When the 'xtalkcor' option is selected but no corrrection is
	performed, either because it was done previously or an error
	occurs, then various warning messages about deleting non-existent
	files will occur.  One way the crosstalk operation will fail is if
	the crosstalk calibration file is not found due to a missing
	XTALKFIL keyword, an error in specifying the file to use, or the
	file is not available.  When the error in ccdproc happens in the
	various combine scripts (zerocombine, flatcombine, etc.) with
	process=yes, this will abort these scripts.

	When the error occurs in running ccdproc directly, the warnings can
	be ignored or the crosstalk option can be turned off.  When this
	occurs in the combine scripts, causing them to abort, turn off the
	process option or the xtalkcor option in ccdproc.

STATUS:	The bug is due to a typo introduced during the last change to this
	task.  The bug is fixed in V4.7 of mscred.
