This should fix any lurking problems with %m in a prompt crashing the
shell.  We don't assume we can write to the return value of getsparam() any
more, which probably wasn't a good assumption at the best of times.  This
is general enough that I haven't looked further down, but I would assume
that we were getting back a "", which gcc would have put in the text
segment, but behaviour with other compilers would differ.  Hence the
variable experiences.
