In our log message, we tend NOT to say "This commit does X" or "X is
done", because such a statement is often insufficient to illustrate
if the commit indeed does X, and explain why it is a good thing to
do X in the first place.
Instead, we
- first explain that the current system does not do X (in present
tense, so we do NOT say "previously we did not do X"), then
- explain why doing X would be a good thing, and finally
- give an order to the codebase to start doing X.
For this change, it might look like this:
The "git worktree list" shows the absolute path to the working
tree, the commit that is checked out and the name of the branch.
It is not immediately obvious which of the worktrees, if any,
are locked.
"git worktree remove" refuses to remove a locked worktree with
an error message. If "git worktree list" told which worktrees
are locked in its output, the user would not even attempt to
remove such a worktree.
Teach "git worktree list" to append "(locked)" to its output.
The output from the command becomes like so:
$ git worktree list
/repo/to/main abc123 [master]
/path/to/unlocked-worktree1 456def [brancha]
/path/to/locked-worktree 123abc (detached HEAD) (locked)

At the first glance, the above gave me an impression that you'd be
adding "(unlocked)" or "(locked)" for each working tree, but that is
not the case. How about keeping the original sentence intact, and
adding something like "For a locked worktree, the marker (locked) is
also shown at the end"?

Is this because for the primary worktree, worktree_lock_reason()
will always yield true?
... goes and looks ...
Ah, OK, the callers are not even allowed to ask the question on the
primary one. That's a bit strange API but OK.
Writing that on a single line would perfectly be readable, by the
way.
if (!is_main_worktree(wt) && worktree_lock_reason(wt))
strbuf_addstr(&sb, " (locked)");
