More on that:  Host is openbsd 4.5, where sh actually is ksh.
http://www.openbsd.org/cgi-bin/man.cgi?query=ksh&apropos=0&sektion=0&manpath=OpenBSD+4.5&arch=i386&format=html says:

"""The default prompt is `$ ' for non-root users, `# ' for root.  If ksh
is invoked by root and PS1 does not contain a `#' character, the default
value will be used even if PS1 already exists in the environment."""

Curiously, "sh" man page doesn't say that... but sh still does it.

Changing the PS1 sent by tramp to include '#' (i.e. "#$ ") works around
that shell behaviour.
