+Subject: [PATCH] search: use boolean prefix for filenames in diffs, too
+Message-ID: <20180720072141.GA15957@example>
+
+Filenames within a project tend to be reasonably stable within a
+project and I plan on having automated searches hit these.
+
+Also, using no term prefix at all (the default for searching)
+still allows probabilistic searches on everything that's in a
+"git diff", including the blob names which were just made
+boolean.
+
+Note, attachment filenames ("n:" prefix) will stil use
+probabilistic search, as they're hardly standardized.
