Use a default path in exec*p*() if PATH is unset?

Possibly not, as it would also require to check whether PATH is set 
later in the command line.

Always using execv() if -i is specified would break:

   env -i PATH=/bin:/usr/bin prog

To force execv()-like behavior with -i, simply use

   env -i PATH=. prog
