That's a great function, I love seeing all the results in an xref buffer. I
previously explored adding a command to the xref similar to
'xref-query-replace-in-results' that pre-populates the FROM field with the
item you were searching for when you executed 'project-find-regexp'.

Unfortunately I couldn't find a way to make that work- I couldn't find a
function or variable referring to the item being cross referenced in the
context of an xref buffer. If I understand correctly, xref only seems to be
concerned with logic to deal with xref results that it is provided. With
that assumption I couldn't really think of a way to architect a good
solution without modifying xref in a way that violates [what I understood
to be] its intent. I'm definitely open to suggestions on how to make that
work, though.
