[Tagging] Automated edit of company name change

[Andrew Errington]

Hello everyone,

Here in Korea a chain of convenience stores has changed its name 
from "FamilyMart" to "CU".  All of the stores have had their signage and 
livery removed and replaced with new signage and livery.

What is the best way to perform essentially a country-wide search-and-replace 
for objects tagged shop=convenience, name=FamilyMart to change the name to 
name=CU?  The objects could be nodes or areas.

Naturally I want to follow the Mechanical Edit Policy properly, the first step 
being to raise the matter on this list.  I'd like to know how to actually do 
this task, so that when we discuss it on the talk-ko list I know how much 
work will be involved both to do the change, and to verify the results.

It is also quite possible that a Mechanical Edit is the Wrong Answer, and it 
would be better for me to encourage mappers here to coordinate our efforts 
and update different areas by hand.

Best wishes,

Andrew
