    duplicate-line: fix optional argument and add test (bug#46621) · 47374d44
    Mattias Engdegård authored 
    The test assumes that the current semantics are intended and desired,
which may or may not be true, but it's better than not having any at
all.

* lisp/misc.el (duplicate-line): Don't crash if called with no argument.
* test/lisp/misc-tests.el (misc--duplicate-line): New test.
