Some problems I see with it, by order of decreasing importance:
- I fail to see in which circumstance(s) this is useful.
- What if the user uses scsh/emacs for his shell.
- Most scripts don't setup much of environment.
- AFAIC things like ~/.cshrc are not a scripts but a config files.
- The call-process needs to quote `script' (and should probably be
replaced by process-file).
- The prompt should start with a capital.
