cargo new does not detect author name and email for author field

[joshtriplett]

/tmp$ cargo new --bin hello
/tmp$ cat hello/Cargo.toml 
[package]

name = "hello"
version = "0.0.1"
authors = ["josh"]

I have $NAME, $GIT_AUTHOR_NAME, and $GIT_COMMITTER_NAME all set, and likewise for EMAIL. git knows who I am:

/tmp/hello$ git add .
/tmp/hello$ git commit -m 'Initial commit'

Aha! I was unaware of GIT_AUTHOR_NAME and GIT_COMMITTER_NAME. Currently we read user.email and user.name from ~/.gitconfig or cargo-new.name and cargo-new.email.

Should be easy enough to add though!

Ideally you don't want to duplicate the logic from git to detect the user's name and email address. Git reads NAME, GIT_AUTHOR_NAME, GIT_COMMITTER_NAME, and user.name for the name, and EMAIL, GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and user.email for the email. I don't actually know what order they're read in, other than that AUTHOR and COMMITTER are used for the author and committer information, respectively.

git var GIT_AUTHOR_IDENT may help:

$ GIT_AUTHOR_NAME='Bon Bon' GIT_AUTHOR_EMAIL='bon.bon@example.com' git var GIT_AUTHOR_IDENT
Bon Bon <bon.bon@example.com> 1430212753 +1200

Triage: still an issue.
