Well, it doesn't necessarily have to display as 0300. As long as we
know it's an integer field, and it's 4 digits long, we can zero pad
the value for sorting but store and display it without leading zeros.

In the short term, while I think of a way to specify a suffix in 
the markup, you could add the units to the field prompt:

:Distance (km): 300

An advantage of just putting it in the field prompt is that
the units will then appear in a table column heading. And it
requires no new code or markup rule.

Presumably, we'd need to support a prefix as well as a suffix:

:Cost: $25

:Length: 100 m

I use the forms recipe in conjunction with the markup extensions,
so the previous / next links gain a tool tip of the first field
on the form. We could make this use either the [[00123 |+]] markup
(new in pmwiki 2.1) to use a (:title:) or use the value of the
first field as the link text. To me, using the value of the
first field seems a sensible thing to do.
