public boolean isAfterSep(int field) {
			return field > 0 && fieldStates.get(field).caret == 0;
		}
Figure out whether the caret in the given field immediately proceeds a separator.

<p>
In other words, the caret must be to the far left (position 0), and the given field must
not be the first field. If true, the caret immediately follows separator index
{@code field - 1}.

@param field the field index to check
@return true if the caret immediately follows a separator.
