+Currently pick makes the tree box graphics part of the "subject". This\r
+is rather unsatisfactory: the tree graphics should be a field in their\r
+own right.\r
+\r
+However, there is no mechanism in the current setup for allowing 2\r
+fields to have fixed combined width but variable individual\r
+width. Thus making the tree graphics a seperate field means that we\r
+cannot keep the current display which is \r
+\r
+date (12 characters) authors (20 characters) tree+subject (54 characters) tags\r
+\r
+We solve this by extending the format specifier. Previously this was a\r
+list of cons cells (field-name . format-string) We now allow the\r
+left-side (the field-name) itself to be a list of cons cells in which case we\r
+apply the formatting recursively.\r
+\r
+This means we can separate the tree box graphics into their own field\r
+while maintaining the current format.\r
+\r
+Note that this will mean that people who have customised the\r
+result-format will need to update their customisation.\r
+\r
+The patch is larger but relatively simple.\r
+\r
+Patch 1/4 is unrelated except I found it while doing this update: we\r
+consistency we should print () for messages with no tags.\r
+\r
+Patch 2/4 is large but trivial: it moves the insertion up a level in\r
+preparation for the recursive formatting.\r
+\r
+Patch 3/4 is also simple: it just allows the recursive formatting.\r
+\r
+Patch 4/4 separates out the tree field. This patch is large as\r
+it allows separate tree faces (matching and non-matching). The\r
+"genuine code" part of the patch is relatively small.\r
+\r
+Finally, this is the last series (apart from some extra tests and\r
+keeping up with mainline progress) that I think pick needs before it's\r
+ready for consideration in non-contrib mainline.\r
+\r
+Best wishes\r
