Inconsistency in git credential helper docs

Hello,

There appears to be a small inconsistency / bug in the documentation
located at https://git-scm.com/docs/gitcredentials.

Under the "Custom Helpers" subhead, there's a line that reads

Generally speaking, rule (3) above is the simplest for users to specify. Authors of credential helpers should make an effort to assist their users by naming their program "git-credential-$NAME", and putting it in the $PATH or $GIT_EXEC_PATH during installation, which will allow a user to enable it with git config credential.helper $NAME.

Earlier in the document, under "Configuration Options > helper", there
is a line that reads

The name of an external credential helper, and any associated options. If the helper name is not an absolute path, then the string git credential- is prepended

I think the latter text is correct. The maintainers of the google
cloud SDK followed the advice in the first part, naming their cred
helper `git-credential-gcloud.sh`, which is not accessible if you set
the custom credential helper to `gcloud.sh`. I had to make a symlink
at `credential-gcloud.sh`, following the instructions in the latter
block, to make it work. One could of course just specify the full path
in .gitconfig, but I figured it might be good to have these parts be
consistent anyways.

Best,
Chris
