octave: libinterp/corefcn/variables.cc annotate

annotate libinterp/corefcn/variables.cc @ 26167:247126168d23

Don't remove globals when 'clear' called without arguments (bug #39790). * NEWS: Announce change. * variables.cc (Fclear): Do not clear the global workspace when called without arguments (matches Matlab behavior). Rewrite documentation. Add a BIST test.
