uid and gid problem

[Martin Pala]

I tried to find some way to solve uid and gid problem to allow its usage 
as standalone statement in addition to its usage in exec statement. I 
think the change of the uid and gid ('useroption') will involve too much 
extra code (present version is very simple and effective, but restricted 
to predefined usage).

We can keep present simplicity by renaming 'uid' and 'gid' options in 
exec statements to 'euid' and 'egid' (which is exactly what it in fact 
is) => 'uid' and 'gid' tokens will be freed for its own statement usage 
(which again is in fact what it is - real owner and group).

So new statement could seem like:

check file bar with path "/foo/bar
 uid root
 gid wheel
 if size was changed then exec "/ab/cd -o option" as euid nobody and 
egid nobody


What about it?
