@krobelus observed in jonas#1370 that this behavior, fixed in ca0809d, regressed again in 2280734. This bug is similar to, but not identical with, jonas#1369. The easiest way to observe the bug is to run `tig blame +28 tig-2.5.12 -- src/diff.c` and press `,` AKA `:parent`. The problem is that the view stays on line 28 instead of jumping to the corresponding line. The test is almost an exact copy of the test by @krobelus from jonas#1370.
This fixes the bug described in the parent commit. `blame->lineno` is only used here and in jonas#1370, so we can either do this or we could shift all the entries in `blame->lineno` by 1.

tig blame +28 tig-2.5.12 -- src/diff.cand press,AKA:parent. The problem is that the view stays on line 28 instead of jumping to the corresponding line.This PR is complementary with #1370, they fix different bugs and can be merged independently. We could also decide on a different solution of changing the meaning of
blame->line. That would also require a change to #1370.See #1370 (comment) and the following comment for more details
A lot of this work is based heavily on that of @krobelus; the test is almost an exact copy of the test from #1370 for example.
