If you are in your local module, you might want to visit the repository without
knowing the repo name or typing the name in.
This adds `npm bugs .` and `npm bugs` so that the npm-bugs-command behaves like
`npm install`, `npm docs`, `npm home`, and `npm repo.`
Also fixed the parsing of `./` (instead of `.`).
Closes #4204.
This feels so good. lib/utils/log.js is the worst kind of
glue code that keeps the npm project from being properly
abstracted into independent pieces.
In the process, also cleaned up a lot of unproductive logging,
and made the npm-debug.log generated on errors be a bit more
easy to read.
