Toolshed part 2 (#18997)

* fixe

* Save work.

* Rune-aware parser.

* oogh

* pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests pass tests

* Publicizes a lot of common generic commands, so custom toolshed envs can include them.

* i think i might implode

* Tests.

* a

* b

* awa
