Stop checking status of a shpec file.

@hlangeveld I pulled this out of #59. It should close #65, but as it stands it won't work. See comments below.

Even in the original branch, ${_shpec_file} is not defined here. If there's not an easy way to get the name of the file, I'd rather just omit that part for now.

Also, I was unable to find any documentation on the -u option for printf. What does it do, is it needed, and can we use our internal echoe instead?

[hlangeveld]

Uh-oh, I morphed $file into $_shpec_file in a premature attempt to use a reserved namespace for shpec internal variables.

I need to check on -u, hangon ...

Yeah, that needs to go. POSIX Shell & Utilities says

OPTIONS

    None.

What -u <fd> is expected to do, is to change the output fd. It's more concise than the traditional >& 2, and that's what it will be...

Closing in favor of #71.
