Bash completion should fall back to defaults after --

[keeperofdakeys]

When using cargo run bin=something --, the cargo bash completion script still tries to complete cargo commands, and does not use normal file completion. Instead it should restore normal bash completion behaviour after the --, so you can complete file names as arguments to the something program.

the -- can refer to rustc options too

[keeperofdakeys]

Even for cargo rustc, only cargo's options are available for tab completion after the --. I've re-enabled cargo's bash-completion temporarily, and confirmed that this issue still exists.

It would be even better if the bash completion could do normal file completion for non-option arguments in these cases (like simple cargo run <my-config-file>).
