RE: add a blank line when a commit has no parent in log output?

Kyle:

Need you to whip up a patch (back port it to current Cygwin git too), see below. It will help with cleaning up Cresaptown branches. Or if you think Watson can do it, give it to him.

Hi Jason,

Take this git log --format="%C(auto) %h% ad%d% s%C(green)% aE" --graph --date=short

One might assume 5505e019c2 and 3e658f4085 are related. But git cat-file -p 5505e019c2

Is there a way to have it look like:

| | | *  5505e019c2 2014-07-09 initial xxxxxx@xxxx
| | |
| | | *  3e658f4085 2019-09-10 (wiki/wip-citest, origin/wip-citest) Added defau
| | | *  ad148aafe6 2019-09-10 Added default CI/CD Jenkinsfile (from f7daf088)

Or

| | | #  5505e019c2 2014-07-09 initial xxxxxx@xxxx
| | | *  3e658f4085 2019-09-10 (wiki/wip-citest, origin/wip-citest) Added defau
| | | *  ad148aafe6 2019-09-10 Added default CI/CD Jenkinsfile (from f7daf088)

If you remove '--graph', then you can add '--show-linear-break' [1]. Unfortunately
these two options do not work together. I think your suggestion to have the '*'
be changed to '#' for root commit is a great idea.

Patch description

When --graph is used

--show-linear-break converts the * to a #

--show-linear-break=x converts the * to a x

In the mean time, I use this trick:

     git log --date=short --format='%C(auto) %h% [%<(2,trunc)%p] ad%d% s%C(green)% aE'

This adds the abbreviated parent hashes (%p) but truncated to 2 characters ([2], [3]). So
the brackets will be empty for root commits.

Cheers,

Philippe.
