Subject: [PATCH] tidy features: use 2-parameter form of internal try macro for
 open err

This tiny patch merely applies @bluss's suggestion for how to get a more
informative error message when the feature check can't open a file, a
matter that had briefly annoyed the present author, leading to the
filing of #38417.
