[elpa] externals/auctex cebf8cc 16/62: Enable lexical-binding for texmathp.el

[Tassilo Horn]

branch: externals/auctex
commit cebf8cc1e534d6fa5e883b5a874a6a37e32a9b88
Author: Tassilo Horn <tsdh@gnu.org>
Commit: Tassilo Horn <tsdh@gnu.org>

    Enable lexical-binding for texmathp.el
    
    * texmathp.el (texmathp-compile): Use `push' on places rather than `set' and
    `symbol-value' on locals partly pointing to symbols naming globals.
