I haven't looked at the patch yet, but I can describe the desired
change in user-facing behavior with an example:

Suppose tags-case-fold-search is true in a buffer with a tags table
containing the symbol "CamelCase".

The key sequence M.camelcase will find the definition of CamelCase.
On the other hand, with the current behavior, the key sequence M.cTAB
will show a completion buffer that does not contain "CamelCase".

With a proper fix, the completion buffer will include "CamelCase".
