A numeric field with no digits is Intermediate, since digits can be
typed into it. The testing for this was complicated by the fact that a
sign might be either a sign in the field or the start of a following
separator.
Break out the testing of separator matching at the start of a view.
This simplifies the existing checks for full separator match and we
can use it in the no-digit numeric field's handling to make the check
more robust (matching the whole separator, rather than only its first
character). It incidentally prepares the way for other changes.
