Actually let's not go down this route because this would mean
that the glob(3) path will never have the same functionality
since it cannot possibly see CTLESC.

My inclination is to just drop the /d\ev issue and use the bash

It's such an unlikely case as why would anyone knowingly put
backslash into a variable and expecting pathname expansion to
remove it without actually using real magic characters.
