New Revision: 287296
URL: https://svnweb.freebsd.org/changeset/base/287296
Log:
sh: Add set -o nolog.
POSIX requires this to prevent entering function definitions in history but
this implementation does nothing except retain the option's value. In ksh88,
function definitions were usually entered in the history file, even when
they came from ~/.profile and the $ENV file, to allow displaying their
definitions.
This is also the first option that does not have a letter.
