SOLUTION DELETED

New awk added a substitute function that can get rid of unwanted fields
whild preserving the spacing in the rest of the record.  For example,

	sub($1, "", $0)

should get rid of field on while leaving the remainder of the record
intact (including spacing).  Repeating the above command should get
rid of field one and two.  An alternative, in one statement is

	sub($1 "[ 	]*" $2 "[ 	]*", "", $0)

where each set of square brackets contains a tab and a space.

Remember to preserve $1 and $2 if the logic of the program requires
them at a later point in the code.
