hook_update_N documentation uses dead links

Good catch, thanks!

I think we should also remove the link to http://drupal.org/documentation/version-info -- it doesn't seem at all relevant. The Git page you referenced has all the necessary information I think?

And maybe if this is the only information we're including about releases and numbers, that link should be moved up to the paragraph that currently says:

A good rule of thumb is to remove updates older than two major releases of Drupal. See hook_update_last_removed() to notify Drupal about the removals.

I think what @jhodgdon meant was to integrate the link in the referenced paragraph. At least that makes sense to me. And also: Given that the list now only contains one single item, it should not be a list, but should be integrated in one sentence ("For further information about releases and release numbers see @link ...").

That's good, just don't put the link text in parentheses:
+ * @link http://drupal.org/node/711070 (Maintaining a drupal.org project with Git) @endlink
(sorry, I missed that in your original patch)

See
http://drupal.org/node/1354#links

That looks good! Thanks. And by the way, set an issue status to "needs review" to trigger the testing bot. :)

Note: Does not apply to the @link line.

I think it's best to limit this patch to fixing the issue reported and the text right around there. We're cleaning up general documentation issues (such as 80-character lines) in
#1310084: [meta] API documentation cleanup sprint
if you would like to help with that effort. Thanks!

Thanks! I think this is ready to go now.
