Thank you very much for the report and patch!
I've made the following slightly different change.
The additional (first) part is necessary to prevent this improper failure:
$ touch -cm no-file
touch: failed to get attributes of `no-file': No such file or directory
Now, it works like this:
$ ./touch -c no-file || echo fail
$ ./touch -cm no-file || echo fail
$
