1) Both singular and plural should end with ".":
​https://build.trac.wordpress.org/browser/trunk/wp-admin/link-manager.php#L111

%s link deleted.
%s links deleted -> %s links deleted.

2) Option name shouldn't end with "." for consistency with the other options:
​https://build.trac.wordpress.org/browser/trunk/wp-admin/options-discussion.php#L91

Show comments cookies opt-in checkbox, allowing comment author cookies to be set

3) The ending punctuation "." should be outside the “Run the installation” mention:
​https://build.trac.wordpress.org/browser/trunk/wp-admin/setup-config.php#L412

After you've done that, click “Run the installation.”
After you've done that, click “Run the installation”.
