Looking at these drawings reminded me of a tangent that is brought
up from time to time. We do not do great job when showing multiple
roots.
If you have a history like this:
A---D---E
/
B---C
drawing the graph _with_ the merge gives a reasonable representation
of the entire topology.
* 46f67dd E
* 6f89516 D
|\
| * e6277a9 C
| * 13ae9b2 B
* afee005 A
But if you start drawing from parents of D (excluding D), you'd get
this:
* e6277a9 C
* 13ae9b2 B
* afee005 A
and the fact that B and A do not share parent-child relationships is
lost. An easy way to show that would be to draw the bottom three
lines of the full history output we saw earlier:
| * e6277a9 C
| * 13ae9b2 B
* afee005 A
either with or without the vertical bar to imply that A may have a
child.
This is not something that has to be done as part of this series,
but I am hoping that the internal simplification and code
restructuring that is done by this series would make it easier to
enhance the system to allow such an output.
Thanks.
