*Recognize the 'll' and 'j' size modifiers as denoting long long times.
*Recognize '%P' as equivalent to '%b'.
*Give a warning for 'L' length modifier in scanf, which is currently not supported (except when assignment is suppressed).
This may be indicative of dubious code in some cases, but it can also have valid use cases that are not easy to modify.
If desired, this could be re-enabled under a separate lint flag (analogous to -Wformat-nonliteral in GCC/Clang, which is available as an option but is not included in -Wformat or -Wall).
It is now stricter about invalid length modifiers. Also, "comp" is accepted where a floating-point type is expected (like the others, it is promoted to extended), and size specifiers are allowed with %n (now pretty much supported in the latest library version).
Mainly, this causes the messages from the format checker to be displayed after the relevant line is printed, along with any other error messages. The wording and formatting of some of the messages is also slightly adjusted, but there should be no substantive change in what is warned about.
