[PATCH 0/4] contrib: pick: allow more general format lines

[Mark Walters]

Currently pick makes the tree box graphics part of the "subject". This
is rather unsatisfactory: the tree graphics should be a field in their
own right.

However, there is no mechanism in the current setup for allowing 2
fields to have fixed combined width but variable individual
width. Thus making the tree graphics a seperate field means that we
cannot keep the current display which is 

date (12 characters) authors (20 characters) tree+subject (54 characters) tags

We solve this by extending the format specifier. Previously this was a
list of cons cells (field-name . format-string) We now allow the
left-side (the field-name) itself to be a list of cons cells in which case we
apply the formatting recursively.

This means we can separate the tree box graphics into their own field
while maintaining the current format.

Note that this will mean that people who have customised the
result-format will need to update their customisation.

The patch is larger but relatively simple.

Patch 1/4 is unrelated except I found it while doing this update: we
consistency we should print () for messages with no tags.

Patch 2/4 is large but trivial: it moves the insertion up a level in
preparation for the recursive formatting.

Patch 3/4 is also simple: it just allows the recursive formatting.

Patch 4/4 separates out the tree field. This patch is large as
it allows separate tree faces (matching and non-matching). The
"genuine code" part of the patch is relatively small.

Finally, this is the last series (apart from some extra tests and
keeping up with mainline progress) that I think pick needs before it's
ready for consideration in non-contrib mainline.

Best wishes

Mark
