There was also a problem with auto-capitalize-mode and auctex. See
see: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23180
and its solution


In order to avoid, that in Auctex, math-mode constructions like
$A_i$ get expanded to $A_I$ use set `auto-capitalize-predicate' was
set to (lambda () (not (texmathp))) as in the following. However
`texmathp' function doesn't save match data but it's run in
`auto-capitalize' that is installed into `after-change-functions'
hook however such functions (info "(elisp)Change Hooks") must
restore match data otherwise unexpected behavior will appear, as
it's in the case of the following BUG.....
