Modified Files:
        src/bin/sh: eval.c var.c var.h

Log Message:
Fix "export -x" (and its consequences) to behave as originally
intended (and as documented) rather than how it has been behaving
(which was not very rational.)   Since it is unlikely that anyone
is using this, the change should be mostly invisible.

While here, a couple of other minor cleanups:
        . One call of geteuid() is enough in choose_ps1()
        . Fix a typo in a comment
        . Improve appearance (whitspace changes) in find_var()
