Fix range behavior with -0 endpoints (bug #38423) * libinterp/interpfcn/pr-output.cc(octave_print_internal): print base or limit of range rather than using expression base+i*increment which can destroy the signbit of base/limit. * liboctave/array/Range.cc(Range constructor): Move trivial 2-line constructor to .h file. * liboctave/array/Range.cc(matrix_value, checkelem): Return base for first element of array. Return limit of range for end of array if appropriate. * liboctave/array/Range.cc(elem): Move function from Range.h Return base for first element of array. Return limit of range for end of array if appropriate. * liboctave/array/Range.cc(_rangeindex_helper, index): Return base for first element of array. Return limit of range for end of array if appropriate. * liboctave/array/Range.cc(min, max): Use '<=' or '>=' tests to return base or limit if appropriate. * liboctave/array/Range.cc(is_sorted): Place more common test first in if/else if/else tree. * liboctave/array/Range.cc(operator <<): Return base for first element of array. Return limit of range for end of array if appropriate. liboctave/array/Range.h(Range constructor): Put trivial 2-line constructor in .h file. liboctave/array/Range.h(elem): Move function which has become more complicated to Range.cc. * test/range.tst: Add %!tests for corner cases of base and limit of range.
