Everywhere: Fix format-vulnerabilities

Command used:
grep -Pirn '(out|warn)ln\((?!["\)]|format,|stderr,|stdout,|output, ")' \

(Plus some manual reviewing.)

Let's pick ArgsParser as an example:
    outln(file, m_general_help);
This will fail at runtime if the general help happens to contain braces.

Even if this transformation turns out to be unnecessary in a place or
two, this way the code is "more obviously" correct.
