ls-files' --resolve-undo option has existed ever since 9d9a2f4aba
("resolve-undo: basic tests", 2009-12-25), but was never documented.
However, the option has been referred to in the ls-files manual itself
ever since ce74de931d ("ls-files: introduce "--format" option",
2022-07-23), making its omission a bit jarring. Document this option.

The previous descriptions of the file selection options were very easy
to misunderstand. For example:
* "Show cached files in the output"
This could be interpreted as meaning "show files which have been
modified and git-add'ed, i.e. files which have cached changes
relative to HEAD".
* "Show deleted files"
This could be interpreted as meaning "for each `git rm $FILE` we
ran, show me $FILE"
* "Show modified files"
This could be interpreted as meaning "show files which have been
modified and git-add'ed" or as "show me files that differ from HEAD"
or as "show me undeleted files different from HEAD" (given that
--deleted is a separate option), none of which are correct.
Further, it's not very clear when some options only modify and/or
override other options, as was the case with --ignored, --directory, and
--unmerged (I've seen folks confused by each of them on the mailing
list, sometimes even fellow git developers.)
Tweak these definitions, and the one for --killed, to try to make them
all a bit more clear. Finally, also clarify early on that duplicate
reports for paths are often expected (both when (a) there are multiple
entries for the file in the index -- i.e. when there are conflicts, and
also (b) when the user specifies options that might pick the same file
multiple times, such as `git ls-files --cached --deleted --modified`
when there is a file with an unstaged deletion).

This is a nice fix: make it clear to the user that only files in the

Yes, I'm aware.
If you're suggesting adding this text at this point in the document,
it occurred to me already, but I chose not to put it here. The reason
is that this is a brief synopsis. The "relevant file selection
options" of this brief synopsis could also be expanded to mention what
they are or what the default selection is or whatever. But folks can
read on to learn that `deduplicate` can be used to remove duplicate
options. Likewise, anyone who reads the text about "relevant file
selections" and wants to learn more is inclined to read on to the
other options to find out.
In contrast, no one will be motivated to read on to find out that
files can be printed multiple times if we don't mention it right here.
And they are likely to get confused when it happens, thinking it is a
bug (in fact, I can point out emails from the archives where that has
happened). Without mentioning the possibility of multiple files at
this point, we have a discoverability problem.
There is no similar discoverability and negative-surprise problem I
can think of by omitting other details, so there is no need to expand
this brief synopsis any further.
The one place we could potentially change thing that might help, is
moving the text about -c being the default from under the -c option
and putting it here. That's a toss-up to me, but for now I elected to
keep it where it is.

Well, you are right. It may be better to be concise here, telling users too
much will make it difficult to read.

Much like the file selection options we tweaked in the last commit, the
status tags printed with -t had descriptions that were easy to
misunderstand, and for many of the same reasons. Clarify them.
Also, while at it, remove the "semi-deprecated" comment for "git
ls-files -t". The -t option was marked as semi-deprecated in 5bc0e247c4
("Document ls-files -t as semi-obsolete.", 2010-07-28) because:
"git ls-files -t" is [...] badly documented, hence we point the
users to superior alternatives.
The feature is marked as "semi-obsolete" but not "scheduled for removal"
since it's a plumbing command, scripts might use it, and Git testsuite
already uses it to test the state of the index.
Marking it as obsolete because it was easily misunderstood, which I
think was primarily due to documentation problems, is one strategy, but
I think fixing the documentation is a better option. Especially since
in the intervening time, "git ls-files -t" has become heavily used by
sparse-checkout users where the same confusion just doesn't apply.

Good to see these tags describe are changed, especially "K" (reader
don't know what is "to be killed")
Maybe we should mention which option will output these tags?
e.g. default -> "H"/"S" ,`--other` -> "?", `--modified` -> "C",
`--killed` -> "K"...

We could, but...
* It's H/S/M, not just H/S that is shown by default.
* It gets weird because other options aren't added to the default,
so if someone specifies "-m" then suddenly H/S/M go away...unless they
also specify "-c".
Trying to explain all that feels like we're getting close to repeating
the documentation of the individual options. But maybe we could just
ignore everything around default behavior and find a way to be brief
such as with:
Note that H, S, and M entries are shown with --cached; R entries
are shown with --deleted, C entries are shown with --modified, K
entries are shown with --killed, ? entries are shown with
--others, and U entries are shown with --resolve-undo.
I'm not sure if I like the documentation better with or without this
added paragraph. What do others think?

What you mean is that each tag will appear in which commands, rather than
each command will have which tags. I think this segment is pretty good.
