# (*) If notmuch new was not run we've got "Processed 1 file in almost

# test created directory document in the database but this document
# was not linked as subdirectory of $MAIL_DIR. Therefore notmuch new
# could not reach the cur/ directory and its files in it during
# recursive traversal.
#
# XXX: The above sounds like a bug that should be fixed. If notmuch is
# creating new directories in the mail store, then it should be
# creating all necessary database state for those directories.
