IWBN to add to the comment about exiting without creating an index not
being an error, e.g. provide an example.
Is it because the file could be stripped? [If it is stripped, should
the script fail or pass? Dunno.]
IWBN to put "${file}.gdb-index" in its own variable so that there's
just one instance.
LGTM with the above nits.
