It seems like a plain bug for bash to do what it does (does it also
turn a symlink into a plain file?  wouldn't that also be a bug?), but
I wonder: what could Tramp do instead of setting HISTFILE to /dev/null?
Could unsetting it result in the same behavior (i.e. not save Tramp's
commands to any file)?
