[Emacs-diffs] master a92e7b4: Don’t set print-escape-newlines in the minibuffer

[Paul Eggert]

branch: master
commit a92e7b4ef6915e079a97e4e33e45b11508170cb1
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Don’t set print-escape-newlines in the minibuffer
    
    This appears to be an unnecessary and possibly-confusing
    revenant from ancient code (Bug#31251).  See thread containing:
    https://lists.gnu.org/r/emacs-devel/2018-04/msg00654.html
    * src/minibuf.c (read_minibuf): Do not set print-escape-newlines.
    * src/print.c (syms_of_print): Do not defsym print-escape-newlines
    or print-escape-control-characters, as these symbols are not used
    in C code.
