Comment:

 Thanks for the initial review:

 * Apologies those commits where a bit all over the place. I've no made
 `git rebase` my friend and will try to push tidier sets of commits in
 future :). I've split the identation and code changes from `a454cd93b`
 into separate commits.

 * I've added an argument to rend_cache_lookup_entry() so that it can also
 be used to query the service-side descriptor cache.

 * The code:
 {{{
 for (i = 0; i < smartlist_len(descs); i++)
         rend_encoded_v2_service_descriptor_free(smartlist_get(descs, i));
 }}}
   was already in `upload_service_descriptor()`. I didn't want to change
 that while adding more code, should I add a commit to change that to the
 `SMARTLIST_FOREACH` style?

 * Yes, that stored log message is still output after `997d596`.

 * I've add a short description of `rend_service_cache` where is is defined
 in the `rendcache.c`.

 I've pushed a new rebased branch which contains the suggestions you made
 at https://github.com/DonnchaC/tor/pull/2/commits. FYI GitHub has a ?w=1
 option which hides whitespace changes in the displayed diff:
