add 'gohack list' or shell completion support about gohack HOT 4 OPEN

Would go list (with suitable flags) not suffice here, for both? I say that assuming shell completion can be made to work given the line-based output of a command

from gohack.

go list -m all is a decent approximation. But gohack can do a bit better, by also indicating which modules are currently being hacked on (and what directory they are in). For the modules that are also being hacked on, it could also print whether the hacked version is dirty. Also, go list -m all emits version numbers, which aren't as relevant for gohack.

Maybe the command should be gohack status.

Erm. There is already a gohack status.

I was about to start working on a PR, but I think I'll wait for more feedback.

go list -f can probably give us whatever we need from a completions perspective, but the status showing "dirty" for -vcs hacks would definitely be useful.
