As OPT_BOOL("patch") natively takes "--no-patch" to flip the bool
off, an int variable "patch" that is initialized to 1 would make it
more readable by avoiding double negation !no_patch like the one we
see below. I guess the reason behind the contortion you wanted to
give the synonym --silent to it?

Other than that small "Huh?", the code looks good to me.

This makes sure that -p and --patch produces the same output as the
default case? I am not sure who in the parseopt API groks the
single letter "-p" in this case offhand. Care to explain how?
The other side of the test to see -s/--no-patch we see below also
makes sense.

Quote EOF to allow readers skim the contents without looking for and
worrying about $substitutions in there, unless there are tons of
offending code in the same script already in which case we should
leave the clean-up outside this primary change.
