Avoid displaying upgrade notice if any output is redirected. This also
alleviates the need to specifically check for `gh completion -s
<shell>`, `gh __complete`, and other scripting scenarios where we
absolutely don't want to trigger any upgrade checks or notices.
Here are the statuses:
- 0: success
- 1: misc. error
- 2: user interrupt/cancellation
- 4: authentication needed
These old exit codes are now changed to "1":
- we used to return "2" for config file errors;
- we used to return "2" for alias expansion errors;
- we used to return "3" for alias runtime errors.
I do not believe that there is a need to distinguish these specific
cases via exit status, and converting them to "1" frees codes "2" and
"3" for more practical use.
This keeps git operations working even when PATH is modified, e.g. `brew
update` will work even though Homebrew runs the command explicitly
without `/usr/local/bin` in PATH.
Additionally, this inserts a blank value for `credential.*.helper` to
instruct git to ignore previously configured credential helpers, i.e.
those that might have been set up in system configuration files. We do
this because otherwise, git will store the credential obtained from gh
in every other credential helper in the chain, which we want to avoid.
Before:
git config --global credential.https://github.com.helper '!gh auth git-credential'
After:
git config --global credential.https://github.com.helper ''
git config --global --add credential.https://github.com.helper '!/path/to/gh auth git-credential'
The AUR is a community-based location for PKGBUILDs, Arch's Install scripts.
There is a unofficial PKGBUILD for building and installing `gh` from the git repo.

Dynamically construct the GraphQL query by using the `viewer` connection
if the owner isn't set and the `repositoryOwner(login:"...")` connection
if the owner was set.
Right now the `gist edit` command doesn't write anything to stdout, so
let's keep it that way until we want to intentionally provide some
feedback in the terminal.
