[elpa] externals/tex-parens 56d870b372: make quote detection more robust

[ELPA Syncer]

branch: externals/tex-parens
commit 56d870b3728883e4003e38f53a3ff0fe72abc082

    make quote detection more robust
    
    * tex-parens.el (tex-parens--ignore): When texmathp is
    available, we make the quote detection more reliable.  The point
    here is that we don't want to regard the double quotes in $x''$
    as a delimiter, but we do want to regard them as such in
    $\{\text{``symbols''} a \text{ on } T^* M\}$.
