Typically, use %q instead of %s (or instead of "%s"), to expose various control characters and the like without interpreting them.

This is not really comprehensive; the codebase makes no general guarantee that any returned string values are free of control characters or other malicious/misleading metadata. Not even in returned "error" values (which can legitimately contain newlines, if nothing else).

A side effect of the code audit required by CVE-2024-3727 .

Typically, use %q instead of %s (or instead of "%s"), to expose
various control characters and the like without interpreting them.

This is not really comprehensive; the codebase makes no _general_
guarantee that any returned string values are free of control
characters or other malicious/misleading metadata. Not even
in returned "error" values (which can legitimately contain newlines,
if nothing else).

I glanced through this and the changes I saw looked good, but I made no attempt to check or look for places that weren't changed.
