bug#66657: 29.1; spurious characters inserted at the shell prompt after quitting

[Vincent Lefevre]

After working on an XML file and quitting Emacs, I got the following
characters that appeared in the command line of the shell:

51;33;39M51;34;38M51;35;37M51;36;37M51;36;36M51;37;36M51;37;35M51;38;35M51;38;34M51;39;34M51;39;33M

I was connected by ssh in an xterm to my Termux environment.

This is not reproducible, but I've already got a similar issue in
the past.
