Use flog symbols for drawing commit trees

[jbergstroem]

Flog symbols is a set of icons that a growing set of terminals (kitty, ghostty, wezterm wip) have decided to support via nerd-fonts. It would be visually pleasing to see lazygit use these as well!

Examples in use:

• https://github.com/SuperBo/fugit2.nvim
• https://github.com/isakbm/gitgraph.nvim
• https://github.com/rbong/vim-flog

The screenshots in the example projects you linked to do indeed look awesome, but I get the impression that the symbols only work when you have blank lines between rows. If that's true, it's not an option for lazygit; we don't want to waste so much vertical space.

It seems that the screenshots just adds an extra line for a description? At least this one:

"Superbo" is part of git metadata.

I don't care what these programs do or don't include in their lists of commits (other screenshots had a blank line instead of the metadata line). My point is that in this part of the graph:

you need three lines to draw the graph symbols, but we only have two available in lazygit.

you need three lines to draw the graph symbols, but we only have two available in lazygit.

Took a closer look by testing it out in my terminal and you're right; you do need three.

Closing as resolved since lazy-git needs to fit glyphs in a 2 line-height drawing mode, not three.
