'file delete' documentation explicitly says that "Trying to delete a 
non-existent file is not considered an error." That's regardless of the 
-force option. And that has always seemed to be how it actually works. 
This should be affecting just about everyone otherwise.

So all in all that's a very strange error to be getting. The fact that 
it shows up only on Travis of course suggests that there is something 
unusual about the environment there. Can't imagine what it would be 
though; this appears to be a built-in Tcl command misbehaving after all.
