Eli has not commented the NEWS file it but I would prefer to provide
(a) the full/valid commmands, (b) the new, rather than old names,
so that one can easily copy-paste them to GDB CLI to try them.

set|show record full insn-number-max
set|show record full stop-at-limit
set|show record full memory-query
