title update

[iron-udjin]

Hello,

OS: FreeBSD-13-STABLE
tcsh: 6.22.04

I'm trying to set xterm window title for program which doesn't support title change. In ~/.tcshrc I have:

if ($?prompt3) then
    set echo_style=both
    alias postcmd 'echo -n "\033]2;${HOST}: \!#:0:q\007"'
endif

Everything works fine except one very annoying thing: in the tcsh history some commands saved two times. First time - command with arguments, second time - command without arguments + #+timestamp:

$ history 5
  4928    8:59    ls -la
  4929    8:59    ls#+1675925966
  4930    8:59    dmesg
  4931    8:59    history 5

Here is discussion regarding this problem on FreeBSD forum.

Is there a way to solve this problem?

Thank you!
