The customizable user option 'read-regexp-defaults-function' was created
for the following problem: by default, 'occur' uses the last history item
as the default value, so 'read-regexp-defaults-function' could be
customized to get a tag at point as the default value of 'occur'.
Exactly the same situation is with 'query-replace-read-from':
by default, it uses the last history item, so changing the value of
'read-regexp-defaults-function' should also affect the query-replace
like in the patch that I sent to Jon.

xref-find-references-and-replace calls query-replace-read-args
with a non-regexp flag, so I have no idea what new variable
could be created for read-from-minibuffer. It already uses
'query-replace-read-from-suggestions' where the top value
could be the default.
