Finally I found out what my profile is good for: I can abuse it as a clipboard!

@: Welcome to tex.sx! A tip: you can use backticks `\`` to mark your inline code as I did in my edit.

@: Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it).

@: Welcome to tex.sx! Note that you don't have to (and shouldn't) sign with your name since it automatically appears in the lower right corner of your post.

@: I tidied up your question a bit, hope that's OK.

I think your question is answered [here](). (Possible duplicate?)

@: Can you please add a [minimal example](http://meta.tex.stackexchange.com/q/228/1235) that illustrates your problem?

comment Serious problem with \widebar
@Bernard: Oh, right. The old version already had that problem, too, so it appears that the new version is still better. I'll see if I can fix it.

Thanks a lot for the confirmation!

comment Missing character 1 in font bbold11
I like option 2 - thanks! But I'm still rather puzzled: Is this really a name clash? One file is Ubbold.fd, the other is ubbold.fd. Ah, maybe I understand now: Under Windows this is a name clash, under Linux it isn't. Correct?

@egreg: Do you mean "Refresh FNDB"? This is did. Otherwise, can you tell me how to rebuild the font name database?

comment Missing character 1 in font bbold11
I did remove (or rather, rename) ubbold.fd, but then the system didn't find Ubbold.fd ... at the moment I use the unsatisfactory solution of an additional copy of Ubbold.fd in my working directory. Any ideas?

@egreg: Thanks a lot for you help so far. I made a funny test: \IfFileExists{ubbold.fd}{\show\relax}{\show\bye}. Under MiKTeX, this shows \relax, und TeX Live it tries to show \bye although the file ubbold.fd exists!!

@karlkoeller: Strange ... I just even tried removing the MiKTeX folder in AppData\Local, but the error persists.

comment How to avoid widow lines after displayed equations
Great, now it works as I would expect - thanks a lot! It would be great if one could somehow determine the end of displayed math and do the penalty thing there. Of course I'd like to that thing to work for align and friends, too. But I don't use too many different display environments, so it might be possible to do it manually.

comment How to avoid widow lines after displayed equations
Thanks for your answer! I'm not sure at all, but I've got the impression that your code works due to some kind of LaTeX bug: If "one line of text" starts a new paragraph, then it goes to the next page as I want - so far so good. But somehow this only happens because then the first page ends with an empty line which leaves no space for "one line of text". I have no idea at all where this empty line comes from!

comment {(x+y)}^2 or (x+y)^2?
@einpoklum: That's what I was saying all the time: math-wise they do. (And typesetting-wise, the output is fine without braces; see Jobobs' answer. Knuth designed the TeX-engine in such a way that you don't have to type braces in order to get nice output.)

comment {(x+y)}^2 or (x+y)^2?
@einpoklum: What I meant: For me, the parentheses () do already bunch the formula together, so there's no need for braces.

comment {(x+y)}^2 or (x+y)^2?
@einpoklum: Well, I'm a mathematician, so I don't see inappropriate semantics here - why should I surround parentheses with braces? I agree that this feature of the typesetting engine is cumbersome, but it's less a design choice than a limitation of computers from the late seventies, when the choice was made. It would of course be great if LuaTeX or some other engine would offer better typesetting in such a case.

comment Negative phantom
@Fictional: Yes, that's correct. And I wrapped the whole thing into a \mathop so that before and after it you also get the same spacing as for \cos.

comment Negative phantom
I probably wouldn't do it, but in this situation you could use \mathop{\rlap{$\sin$}\hphantom{\cos}} instead of a negative phantom.

comment Why \allowbreak is not working?
Note that, by default, there's no stretching or shrinking of the spaces after commas (\thinmuskip) in math.

comment Drawbacks of redefining math accents with extra leading {}?
@Bruno: The \tilde{b}'_i^2 is the only example so far that I might find convincing; I didn't have time to think about it yet. By the way, I agree with egreg about the "prime squared": in the sixth line of your example, it clearly looks as if the prime is squared (even if the TeX markup speaks diffenrently). A simple \tilde{b}'^2 is much better.

@Bruno: It would be great if you could think up such a case and add it to the question! (I've deleted my previous comment as it was obsolete.)

Very nice application of \scalerel!
