ouch.  I hope Carl reads this and feels your pain :)

It is very similar.  If I saw this patch earlier, I would not care to
write mine.  Comments below.

                        :size (max 8 (- (window-width) notmuch-hello-indent
 -				       (length "Search: ")))
 +				       (length "Search: ") 1 ))

Looks like this results in search widget field 1 character shorter than
we have now.  And hence not aligned with the recent search lines.  I do
not see why we need this.

 -	(widget-insert "\n")
 +	(widget-insert " \n")

That was my first implementation of the patch.  Later I changed it to
make the space invisible, so you can not get to it with C-f and C-b.  A
small improvement IMO.

I wish I saw Kan-Ru Chen's patches earlier.

Regards,
  Dmitry
