ksh 93u+m/1.0.2

[McDutchie]

This bugfix release fixes the interactive shell crashing when one of the predefined aliases (currently 'history' and 'r') is redefined, whether from a profile/kshrc script or manually. This crash occurred in two scenarios:

1. when redefining and then unsetting a predefined alias;
2. when redefining a predefined alias and then executing a shell script that does not begin with a #! path.

Both are fixed now.
