feat(git): git_commits shows the current branch graph

[CyanJoeng]

Description

I'd like to see a graph view in git_commits picker, and notice the closed issue (#1041) when I try to find some solutions.
I'm not familiar with the Lua language, so, a little modifications are written to achieve the basic demand.

Feat # (#1041)
show the current branch graph when viewing git_commits

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Invoking the git picker function builtin.git_commits by a vim key mapping, the the commits log with graph will displayed in the popup window.

NB. commit logs showing with graph will insert extra entries with no SHA value, so a error msg will shown in the vim msg bar if these extra entries selected.

I gave it quick test. It showed a bit of graph on telescope. However, tags/HEAD no longer showing on the commits.

Could you please make it optional change. Thanks

btw: #1041 example is amazing. Wish if this can be produced or configured here. The date thing is pretty useful

[CyanJoeng]

Ops. Sorry for that mistake, and the new commit added the tags/HEAD.

the #1041 example is pretty cool, and I am trying to add colours to get a nicer display.

Cheers 🍻

[kkharji]

LGTM. Indeed I can see the tags/HEAD now.

Please fix the CI failing actions so we can merge.

Any additional enhancement can be done in another pr (tag me)

[kkharji]

won't not msg be always false?

[Conni2461]

i think the check makes sense. its nil (and we enter this branch) if we match a line that has no commit message (its nil because of string.match) but its and empty string if we dont even have a sha, so we do not enter this branch

[Conni2461]

Thanks :)

LGTM

@kkharji feel free to merge, if your last comment is resolved and sorry about the broken CI, i merged something styled wrong into master a week ago and was to lazy to resolve it ^^

Edit: I just rebased the branch, you are still author of the commits :)

[SebTalbot]

This should be optional. It breaks custom git_commands unless we use --graph which forces us to include it.

Also, the help documentation isn't updated and it was pretty confusing.

[petobens]

@kkharji @CyanJoeng for some reason when using git_bcommits I'm seeings lots of empty lines with ... (see image below where I compare telescope output with git-terminal output). Can those lines be suppressed?

Also @SebTalbot is right, documentations need a revamp.
Thank in advance!

[Conni2461]

There is a proposed solution in #2357 which makes things even worse (see #2357 (comment)), so i decided to revert. sorry for the inconvenience, i should have caught and this should have never been merged
