Merge branch 'jk/t0014-dynamic-deprecated-cmds' into next

The alias tests in t/t0014-alias.sh have been updated to dynamically query the list of deprecated commands using 'git --list-cmds=deprecated' to avoid test failures when running with WITH_BREAKING_CHANGES in a build directory that contains stale executables of formerly deprecated commands. * jk/t0014-dynamic-deprecated-cmds: t0014: generate deprecated command names dynamically t0014: factor out choice of deprecated commands
