Emacs 26.1, Linux
When I have this
(setq tramp-histfile-override t)
and use tramp to open a remote directory via scp, the *local*
~/.bash_history is wiped out (i.e. it becomes an empty file). I don't
think that is the desired behavior for this setting.

Thanks for looking into it.

Thanks for the bug report. I've pushed a patch to the Tramp and Emacs
repositories which should fix it. Do you have a chance to test a recent
checkout of Tramp or Emacs?

Well, I have hard times to reproduce your problem. Anyway, could you try
the appended patch instead?

Sorry to reply late.

I could not patch your patch file on my Emacs 26.1 tramp.el. I guess I 
will wait until I get time to have Emacs 26.2 installed and test your 
change again.

Yes, please commit your work.

I have never run tramp outside the stock Emacs, but I can certainly give 
the package-install a try on tramp after you code is in.

Thanks a lot!

That's one way. The other one is that I'll commit it to the Tramp
repository, and with the next Tramp release (2.4.2) you could install
and check it via GNU ELPA. These days, I'm polishing the final bits for this.

Would you like to test a prerelease of what will be Tramp 2.4.2 in GNU ELPA?

I've prepared an intermediate ELPA package Tramp 2.4.1.50 for you. Tramp
as ELPA package will appear for the very first time end of June.

Next message (off-list) I will send two files to you, tramp-2.4.1.50.tar
and archive-contents. Pls copy them into any directory, let's say /tmp.

In your .emacs, add the following forms:

--8<---------------cut here---------------start------------->8---
(require 'package)
(add-to-list 'package-archives '("local" . "/tmp/"))
--8<---------------cut here---------------end--------------->8---

When you open your *Packages* buffer, you'll see an entry like

--8<---------------cut here---------------start------------->8---
  tramp              2.4.1.50      new        local      Transparent Remote Access, Multiple Protocol
--8<---------------cut here---------------end--------------->8---

Install it. Maybe you need to restart Emacs, don't know. When you run
your test, check variable `tramp-version'. It shall have the value "2.4.1.50".

It seems like the problem was fixed in a new version of Tramp?  So is
this still an issue or should it be closed?

I believe this is fixed in recent Tramp. As you have said, there isn't
any confirmation for more than a year, so I'm closing the bug.

I originally reported this bug. Sorry to respond late. I just checked 
with Emacs 26.3 and the bug is still there.

Sure. It is fixed in Emacs 27.1. Or you install the recent Tramp from
GNU ELPA.

Thanks, I've seen this already. But I don't know yet what to say
about. At least, it is on my TODO list.
