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

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
