I was search a regular expression 'mail' in project ~/.emacs.d. This is
part of the result,
--8<---------------cut here---------------start------------->8---
/Users/pankaj/.emacs.d/lisp/init-email.el

Notice the duplicate results from line number 1 and 34.

It looks like when there are two matches in the same line, the line is
listed twice? So I tried the same command on the Emacs tree (with
"regexp" as the regexp) and, indeed:

In bug#36967 it's labeled as a "drawback".

It is both, I guess.
The behavior is less than ideal, but the fix will have to satisfy
multiple constraints: the xref item creation (taking care of the format
being backward-compatible), the rendering of them in the buffer, and the
'xref-query-replace-in-results' command, the implementation of which
relies on the one-line-per-match property of an xref buffer.

Right. I know next to nothing about xref internals... but... couldn't
this function just squash the multiple-matches-on-a-single-line into one
line? Preserving the text props from the multiple lines and whatnot?
So a post-processing step?

Which function?
xref-query-replace-in-results works on an existing xref buffer. And it
uses the position of point (at the beginning of line) as both user
indicator and to persist the state of the replacement process.
Going back to xref buffers, if two matches are rendered on one line,
that leads to a question of how 'n' and 'p' should behave (whether they
would also jump between the matches on the same line).

Then I'm not sure which eventual behavior you envision. Among other
things, it doesn't answer the question I asked in the second paragraph
of my previous email.
And if I get your idea right, this would break
xref-query-replace-in-results.

I have no idea; I've never used those commands.
I'd just expect project-find-regexp to work as M-x grep, and have
`next-error' work (which works based on lines).

So you think it's a good idea for 'n' and 'p' to skip subsequent matches
on the line? I'm less sure, but OK.
Then that mostly leaves the question of xref-query-replace-in-results
and how to retain the information it requires in a backward-compatible way.

Please don't: that would be mightily confusing.

To play the devil's advocate: this is already what both Grep and Occur
do. So maybe it is fine?
Or we should fix the other modes.

I'd prefer the latter, of course.

At least by default, that is. If someone really wants to be able to
skip identical hits, I won't object to having an option for that. But
having 'n' and 'p' skip by default is unexpected and confusing.
