Subject: [PATCH v2] attr: fix instructions on how to check attrs

From: "John Cai via GitGitGadget" <[email-masked]>
Date: Mon, 23 Jan 2023 04:22:21 +0000

From: John Cai <[email-masked]>

The instructions in attr.h describing what functions to call to check
attributes is missing the index as the first argument to
git_check_attr().

When 7a400a2c (attr: remove an implicit dependency on the_index,
2018-08-13) started passing an index_state instance to git_check_attr(),
it forgot to update the API documentation in
Documentation/technical/api-gitattributes.txt. Later, 3a1b3415
(attr: move doc to attr.h, 2019-11-17) moved the API documentation to
attr.h as a comment, but still left out the index_state as an argument.

Fix this to make the documentation in the comment consistent with the
actual function signature.
