Luckily we have a readily=E2=80=93available corpus of elisp code that we can measure. The two=E2=80=93character sequence =C2=AB\"=C2=BB occurs on twelve and a ha= lf thousand lines in just the Emacs lisp source code, often more than once per line. =EF=BD=A2\\=EF=BD=A3 is used on just over 27k lines, and =E2=80=9C\\\= \=E2=80=9D 1604 times. There are 101 lines using =E2=9F=A6\\\\\\\\=E2=9F=A7. =EE=82=B0=C2=A0rg '\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\' textmodes/reftex-vars.el 564: \"\\\\\\\\begin{eqnarray}\\\\|\\\\\\\\\\\\\\\\\" works for eq= narrays. =20=20=20=20 net/tramp-sh.el 962: quoted=3D`echo \"$file\" | sed -e \"s/\\\"/\\\\\\\\\\\\\\\\\\\"= /\"` Look at that! 19 backslashes followed by a double=E2=80=93quote. That=E2=80= =99s just stupid. I wonder if it=E2=80=99s a record? Should we use git blame to find = the names of every person who touched that line and ask them what they think? I can guess what they would say. I think the benefits would add up pretty quickly. db48x
