Re: [Bug] git-credential-netrc.perl is not built and is not available in `exec-path`

Hi,

I'm missing some basic information:
- what platform are you running on?

I'm using Arch Linux with Linux v5.12.5-arch1-1.

- what commands did you use to install Git?

`sudo pacman -S git`

- what are you trying to do?  That can help us with understanding the
  problem or giving better advice tailored to the use case.  The netrc
  credential helper is mostly meant as a demo, since libcurl supports
  ~/.netrc on its own already.

I wanted to use `git-credential-netrc.perl` to use `.authinfo.gpg` as
git credential. The `gitcredentials` manual said use:
`git config --global credential-helper foo`
for using credential helpers. It also mentioned that `git credential-`
gets prepended to the external helpers. So I expected:
`git config --global credential-helper 'netrc'`
to work.

I can use it as a helper if I use an absolute path:
'/usr/share/git/credential/netrc/git-credential-netrc.perl'

After looking at the `PKGBUILD` file in Arch Linux's git repository, I
found out that they are not making "netrc".
https://github.com/archlinux/svntogit-packages/blob/4864e39da0bc99e373f3cb728272a93d66b58cd6/trunk/PKGBUILD#L63-L64

So this is not a bug. As Jeff King mentioned as well.
I should have checked the `PKGBUILD`.

The output of `git --exec-path` is `/usr/lib/git-core`. And there are
other helpers there(made by Arch Linux).
This is the output of `lsd /usr/lib/git-core/ | rg credential`:
git-credential
git-credential-cache
git-credential-cache--daemon
git-credential-gnome-keyring
git-credential-libsecret
git-credential-store

I expected the third-party helpers to be in the output of `git help -a`
as mentioned in the manual. They are not in the `PATH`, but they are in
git's `exec-path`.  So shouldn't they be printed in the help output?
