Everywhere: Fix format-vulnerabilities

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.
