The actual patch series is this.

    http://thread.gmane.org/gmane.comp.version-control.git/95351

The thread the patch series's cover letter refers as "the topic discussed earlier" is this.

    http://thread.gmane.org/gmane.comp.version-control.git/95072/focus=95256

Here is how people can dig this, for people's reference.

 (1) Where in the code is this feature implemented?

     $ git grep -n -e '\.have' -- '*.c'
     builtin-receive-pack.c:647:             add_extra_ref(".have",...
     connect.c:87:               name_len == 5 && !memcmp(".have", ...

 (2) When was it added?

     $ git blame -L 645,650 builtin-receive-pack.c
