Update problem recipe.

Using ra_local, with svn version 83, db-3.3.11, APR and HTTPD from this morning,
I produced the following (greek-repo contains a greek-tree)

The first problem (not getting iota) is due to the fact that adm_crawler.c:
svn_wc_crawl_revisions doesn't check for (on disk) existence of the target
when determining to report it missing.

The second problem is due to the fact that get_editor.c:
svn_wc_get_actual_target is not setting values in a specific case.

If that is fixed, then it will crash, because the entry->ancestor will be
NULL, since it can't find the thisdir entry.

If that is fixed, it will error out because the base_rev will be -1, which is
an illegal value in berkeley db.

If that is fixed, it will error out trying to find the node_id in the
transaction, which has been deleted (rightfully so).

The posted patch is missing the changes to two files: get_editor.c and
adm_crawler.c. Unfortunately, I lost my copy of it, but I will reproduce it
shortly.

The changes in mod_dav_svn are (as Greg noticed), simply anchor target problems,
which could be dealt with later, but the rest are real bugs.

NOTE: my email hasn't been working properly for the last two days, so please
reply to kevin@pilchie.homeip.net for now.
