Allow sub2ind() to accept indices outside the size of the input subscripts (bug #62184)
* NEWS.8.md: Announce change in Matlab Compatibility section.
* sub2ind.cc: Add '#include "utility"' for access to std::swap.
* sub2ind.cc (Fsub2ind): Check nargout to figure out ndims of output.
For special case of vector (1-dimension), put in code to guarantee a
row vector output. Add BIST tests for bug #62184. Remove input
validation BIST which no longer applies.
* Array-util.cc (ind2sub): Remove input validation requiring index to
be within range of subscript size. Adjust code to put all remaining
elements in the final output dimension.
