Fixes for the "run it" command
commit 85e43410:
cerbero/runit: Behave exactly like a wrapper would
Don't print a useless exception when the command that was run fails,
always exit with the returncode of the command, and fix shell quoting
issues.
commit 45248238:
cerbero/runit: Actually run inside the config env
We no longer set the configuration's env on os.environ.
commit d0a60b11:
cerbero/runit: Slurp all remaining arguments
This allows passing all arguments to the command that we will run
without having to use `--`.
