We've recently released AUCTeX 11.89, you can grab it from ELPA ;-) > In case you are wondering, the non-matching brackets [\} appear for > example in physics as so-called "super Lie brackets". Thanks for taking the time to report this bug, I can reproduce it. The culprit is the (re-search-forward (reftex-everything-regexp) nil t) within the `reftex-with-special-syntax' macro in `reftex-parse-from-file' function. Actually in the code it is called as (re-search-forward regexp nil t) I wrote the above line for ease of reproduction. Of course `reftex-everything-regexp' is an undocumented function that returns one of two undocumented variables. I can reproduce the bug only if `reftex-support-index' is non-nil, so in the end the culprit is `reftex-everything-regexp'. There is a simple workaround you can put in your code: close the brackets, also in a comment is fine: [\} % ] But I don't know how to really fix the bug, it's too late for me to decrypt that regexp now. Having a clue of what it should *exactly* match would be of great help.
