Jamie and Barry have mentioned some problems with this approach (inelegant,
undo boundaries not maintained, region commands need special care); there
are a number of others.  For example, consider the following form:

Item:  Door     Quantity:   22
Item:  Jamb     Quantity:  220
Item:  Hnge     Quantity: 2200
Item:  Knob     Quantity: 2222

After inserting an "i" in "Hnge", one would want to end up with

Item:  Door     Quantity:   22
Item:  Jamb     Quantity:  220
Item:  Hinge    Quantity: 2200
Item:  Knob     Quantity: 2222

and not

Item:  Door     Quantity:   22
Item:  Jamb     Quantity:  220
Item:  Hinge     Quantity: 2200
Item:  Knob     Quantity: 2222

Every command (for instance, deletion and insertion) which moves text in
the buffer must also be modified or redefined not to do so.

Multiline rectangular fields that aren't flush left also present a special
problem that I don't know how to deal with.

Unfortunately, though this approach may have flaws, it seems like the best
one nevertheless.  I appreciate the comments so far; are there other
suggestions?
