PATCH: Memorey leak with PS4 usage.

[Felix Rosencrantz <f_rosencrantz@xxxxxxxxx>]

There seems to be a memory leak issue with the use of promptexpand.
I've included a patch for utils.c.

I think there are additional problems with promptexpand's use in subst.c, which
I'll leave for someone who understands the code better.
