Improve copying diffs

Turns out, the LLMs understand diffs perfectly.

Prompting in markdown with diffs as examples work great!

"hey AI, this is how it's done, then put the diff"

example:

However, copying diffs in lazygit is not straightforward

Let's open diff for this file:

lazygit -f app/Models/MyExample.php

• mouse doesn't work
• v doesn't work

• there's no c-0 to copy diff

Implement git show

See the file exactly as it was at certain commit, not as a diff but the hole file.

Like doing git show 0d6b0012:app/Models/MyExample.php

In vim + fugitive you can go to a file and do :0Gclog!

Also, making the code selectable makes it super useful for day to day coding or prompting

Self answered:

copy content of old file with Enter on the commit, then select file, then y

copy diff by selecting a commit (or v to select multiple commits) then Enter then y
