How exactly are you setting your prompt?

This doesn't demonstrate any misbehavior in parameter expansion,
because ${HOST%%.*} does not undergo parameter expansion at all - in
the first line, because it is quoted, and in the second line, because
it is the result of parameter expansion. Try this instead:
$ echo ${HOST%%.*} ${USER}
This way, the HOST and USER parameters are expanded. On my system, it
gives the same output regardless of whether $HOST contains a dot or
whether any existing files match.
