yesterday, when I was checking code for something else I was thinking
the same issue: Instead of the above the code sections:

        /* XXX: Eventually we'll want more sophistication to let the
         * user specify files to be ignored. */
        if (strcmp (entry->d_name, ".") == 0 ||
            strcmp (entry->d_name, "..") == 0 ||
            (is_maildir && strcmp (entry->d_name, "tmp") == 0) ||
            strcmp (entry->d_name, ".notmuch") ==0)
        {
            continue;
        }

and
        /* XXX: Eventually we'll want more sophistication to let the
         * user specify files to be ignored. */
        if (strcmp (entry->d_name, ".") == 0 ||
            strcmp (entry->d_name, "..") == 0 ||
            strcmp (entry->d_name, ".notmuch") == 0)
        {
            continue;
        }

Could be simplified to check just starting dot (.) (and tmp
in add_files_recursive() in case of is_maildir). Maybe
the count_files() function (the latter one above) should
also do the same check so that the numbers count_files()
and add_files() are (almost the) same, causing less confusion
to the user.

I personally don't want to *exclude* more -- I was planning
to hack in code that only include a list of directories under
top level 'db_path'.
