Terminal window hostname always showing

Terminal window hostname always showing

[AC]

Is it possible to turn off the automatic hostname that the window
manager is adding to terminal windows?

Right now, on any machine I log into, they all use escape sequences to
set the title of the window.  However, the window manager (not sure
which I have, looks like xorg-server) on the Cygwin system is adding a
hostname to the title.

I'm using the bash escape sequence "\u@\h: \w" which is supposed to give
me the user and the short name of the host (minus the domain) and the
path.  However, all my terminals on the Cygwin system end up like this:

user@host: ~ @host.example.com

If I change the escape sequence on the remote machine to use the full
hostname, the result on the Cygwin system is:

user@host.example.com: ~

It seems to me that the window manager is interpreting the data in the
escape sequence and opting to put a hostname on the title if it can't
find one that matches the connection.

It does the same thing if I use -T/-n on the remote xterm command.  I
end up with something like

title-used-on-command-line@host.example.com

I've verified that it's Cygwin's window manager doing it by logging in
from a regular Linux box and changing the title manually, no host name
showing up.  I'd like to stop this so the titles are what I set.

This is the data from the xserver log:

Yes, use the X server option -nohostintitle.

Thanks for pointing out this issue.

Almost. When -hostintitle is enabled, the WM adds the contents of 
WM_CLIENT_MACHINE to the window title, unless it already seems to be there.

I've tried to tweak this heuristic a bit in X server 1.17.1-3 so that
if WM_CLIENT_MACHINE contains something that looks like a FQDN, it only 
looks for the hostname part, not the whole thing.

Ah, thanks I had no idea that -nohostintitle existed.  I did a lot of
searching online first before submitting the question so I should have
stumbled across that at some point.  As soon as I get back to that
machine I'll add the option.

I also appreciate the heuristic tweak.  A couple other machines will
benefit from it especially where the windows are very narrow.
