No, that would be:

    "Jan" !"    "!<uary>

The "<uary>" is strictly "insert if not already there".

Imagine the edit:

    dateexp    monexp <" "> {N} [ "," <" "> {N} ]

This will convert "Dec12,2004" into "December 12, 2004".  (Assuming the
field is at least 17 characters long.)  Obviously, there weren't four
spaces to remove after the "Dec".
