Qualified pages with many incoming links

This query lists titles with 100+ incoming links which might be expected to be in italics or quotes and do not have a dab at the base name,
e.g. Abraham_Lincoln_(1930_film).  Links to the page at the base name which are in italics or quotes may be intended for the qualified name.
To reduce run time, it checks one initial at a time with LIKE "A%(%)" etc.
