Sometimes the command fails with a 'type: write error: Broken pipe'.
This is because 'head -1' only reads the first line, then exits.
If 'type' writes the second line after 'head -1' has already exited,
then the aforementioned error is triggered.
We fix this by buffering the entire output of 'type' before
invoking 'head -1'.
It wasn't clear how to update the list of installable Ruby versions after installing rbenv from Git. This is a bit confusing for people who use rbenv to run third party Ruby apps rather than write their own and are less likely to know/care about the distinction between `rbenv` and `ruby-build`. I hadn't touched it for about 2 years and totally forgot that I'd need to manually update ruby-build.
Alternatively, it might be better to make ruby-build a git submodule.
A malicious `.ruby-version` file in the current directory could inject
`../../../` into the version string and trigger execution of binaries
outside of `RBENV_ROOT/versions/`.

This suppressed any output when using RBENV_DEBUG=1 and does not really
hurt to have in the unlikely case that it should fail; you would get
two error messages now:
rbenv: ruby: command not found
rbenv: system version not found in PATH
Command `rbenv version-name > .ruby-version` will create an empty `.ruby-version` file
before running `rbenv-version-file`. This causes `rbenv-version-file` to return empty
string which in turn causes `rbenv-version-name` to return `system`.
Ensure size of `.ruby-version` is non-zero as a workaround.
Shell integration is not enabled by default. This means that, from all the
commands from `rbenv commands`, only "shell" won't work right away.
Replace "no such command" with a more descriptive message that points to
`rbenv init` instead.
* Move Homebrew to the top, common case for new devs
* Note that `brew install rbenv` includes ruby-build by default
* Be clear that `rbenv init` instructions are needed for shell setup
* Be explicit about starting a new shell to pick up PATH/init changes
* Use rbenv-doctor to conclusively demonstrate correct setup
* Separate upgrade instructions for Homebrew vs Git installs

I work on a team that has followed the Homebrew installations. More than once we've missed the `rbenv init` instruction and it has caused headaches down the road. This formatting makes it harder to miss.
The setenv function in fish shell has changed dramatically in
75600b6b53
It now conforms to the csh version, which takes at most two arguments.
In this init script, the form
setenv PATH prepend_something $PATH
had been used, which had too many arguments.
Since setenv isn't a native command in fish, a suitable replacement is
to use the "set -gx" command, which can consume multiple arguments.
