[latexrefman] There is no \PackageInfoNoLine

[Karl Berry]

    I just tried to use \PackageInfoNoLine and failed. I cannot tell why,

Maybe because the \(Package|Class)Info commands only write to the log
file. That's the only difference I can see.

    but \(Package|Class)InfoNoLine are definitely not provided.
    On the other hand, there are \(Package|Class)Note and
    \(Package|Class)NoteNoLine commands for writing informations on the
    screen, which are not listed in latexrefman.

I updated the manual:
https://latexref.xyz/_005cClassError-and-_005cPackageError-and-other-messages.html

Let me know if you come across other errors/omissions/whatever.

There are many commands not included, especially new ones defined in the
last few years (expl3 is basically not there at all), but lacking anyone
having the time and energy to systematically start going through them (a
big job), I'm basically reacting to whatever people report ... --thanks, karl.
