[Emacs-diffs] master eee5372: Fix lisp.h underparenthesization

[Paul Eggert]

branch: master
commit eee537267f8d6a2f5a48f0c26c14546ac922936c
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Fix lisp.h underparenthesization
    
    * src/lisp.h (STACK_CONS, AUTO_STRING_WITH_LEN):
    Parenthesize compound literals that are function call args.
    Although this does not fix any bugs, it is the proper style for
    macro parenthesization as it means this code will continue to
    work even if make_lisp_ptr is changed to a macro.
