Subject: [PATCH 2/3] perf annotate browser: More clearly separate columns
From: Arnaldo Carvalho de Melo <acme@...hat.com>
The first column (columns in the near future) are for the per line event
overhead(s), that only appear when they are not zero.
To clearly separate it, add back a solid vertical line, with just one
colour, not influenced by the per line overheads.
Then have the addr/offset column, then optionally the dynamic
(static in the future) jump->target arrows, if 'j' enables it.
Then the instructions.
