Doesn't work.

.editrc is not even looked for according to strace, at least not in
version 3.1-20191231-2+b1 (I'm using it with the mariadb mysql client).

According to #975911:

: Hi, this is also bugging me on Fedora 32. Digging deep into the
: library chain and source code, it almost certainly is a libedit issue.
: Linux doesn't have issetugid(), and in src/el.c in libedit
: (2019-something thru 20210419 versions) it clearly only reads editrc if
: issetugid is available.


Thanks,
Paul
