Casual and nonchalant bump.

I realize that everyone has their plate full right now (Emacs has tabs!
Face extension beyond EOL is customizable!  What a time to be alive!),
so I am not expecting this to get any immediate attention.  In case it
helps though, here is a comparison when running e.g. sed 's/?/!/':

Old prompt:

> Confirm--do you mean to use ‘?’ as a wildcard? (y or n)

New prompt based on read-multiple-choice:

> Warning: 1 occurrence of ‘?’ will not be substituted.  Proceed?
> ([Y]es, [N]o, toggle [D]etails, [?]):

Hitting 'd' pops a buffer showing more information[1].  The commands
then become:

> ([Y]es, [N]o, toggle [D]etails, toggle [M]arkers, [?])

Hitting 'm' shows/hides '^' markers below the occurrences; 'd' quits the
details window.
