Make safe_asterisk work on dash/sh/bash etc.

Merged from the change to trunk via issue #13111. For some reason
the changes there were only done on trunk, and thus were available
for 1.6.1 and 1.6.2 when they were branched. Because this change is
available on both 1.6.1 and 1.6.2, it makes sense to allow it on the
1.6.0 branch as well.

(closes issue #17094)
