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 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.)

comment Automatically replace all |foo| with \abs{foo}
@Predrag: Thanks for pointing this out. You're right, it has to be gawk, which my machine uses if I ask for awk. Unfortunately I can't edit my comment.

Try gensub: awk '{print gensub(/\|([^|]*)\|/, "\\abs{\\1}", "g", $0)}'

comment Multiline equation with cases
@Marco: Finally I see the effect of the 4mm: the choice influences whether the whole construction will be centered in the math display. With 4mm it's not because the brace construction is wider than that. It's not so nice that the user has to care about this number.

comment Multiline equation with cases
@Marco: Hmm, OK. By the way, I noticed that bigdelim unfortunately doesn't take into account the \arraystretch (which is 1 in your case, so the output is great).

Did you test your sed code? Note that you need \( instead of (! Moreover, note that it's easy to make the sed version non-greedy: just use [^|]* instead of .*.
