BUG: exec permission denied

BUG: exec permission denied

[Mark-Jason Dominus]

It seems that if I try to execute a command `foo' for which I don't have
execute permission, rc gives me `foo not found', which is justifiable if
rc had to do a path search to find `foo', but not justifiable if `foo'
specified a path.  That is:

	; echo $path
	/usr/etc
	; ls -l /usr/etc/shutdown 
	-rws------  1 root        24576 Mar  6  1990 /usr/etc/shutdown
	; shutdown
	shutdown not found

makes sense (although you could argue against it), but

	; /usr/etc/shutdown
	/usr/etc/shutdown not found

is incorrect.

  The night is pleasing to us because, like memory, it erases idle details.

My original note was unclear. The behavior I was complaining about was
not the failure to exec, but rather the error messgae.

I claim it should be `permission denied' instead of `... not found'.

Byron agrees with me on this.

it should say what errno is after the exec returns.

Lest it seem that I agree with something that I don't necessarily agree with,
please let me clarify my viewpoint:

Right now rc prints one, and only one, error message when it cannot find/exec
something: "foo not found". To say that it should print a message that is a
little clearer is nice, but before I go ahead and implement something like
that, I would first want to know how easy it is to do this portably.
