Flags: verbose

[steveklabnik]

This issue is part of #125

-v/--verbose: more verbose output

Using this flag looks like this:

$ rustdoc -v src/lib.rs
$ rustdoc --verbose src/lib.rs

This enables "verbose mode", which means that more information will be written
to standard out. What is written depends on the other flags you've passed in.
For example, with --version:

$ rustdoc --verbose --version
rustdoc 1.17.0 (56124baa9 2017-04-24)
binary: rustdoc
commit-hash: hash
commit-date: date
host: host-triple
release: 1.17.0
LLVM version: 3.9

Should we keep this flag or not?

[steveklabnik]

This seems like a pretty obvious thing to keep. Possibly we should have a quiet flag too!

If a user passed the verbose flag, would we want to forego the spinners and just print all messages to stdout, in addition to verbose-only messages?

[steveklabnik]

Yeah, dropping the spinners and printing out some form of logs seems 👍
