git log --full-diff 的作用

原始文档比较拗口，摘选如下：

--full-diff
Without this flag, git log -p ... shows commits that touch the specified paths, and diffs about the same specified paths. With this, the full diff is shown for commits that touch the specified paths; this means that "…" limits only commits, and doesn’t limit diff for those commits.

说人话，假设你提交了一个 Commit，这个 Commit Z 修改了 文件 A 和 B。

git log without full diff

不带 --full-diff 参数，则在相关 Commits 中只显示特定文件的 Diff，也就是说只显示 A 的变更。

git log -p -- src/components/cmdb/components/A.vue

git log with full diff

带 --full-diff 参数，则在相关 Commits 中除了特定文件的 Diff，还显示这些 Commits 修改的其他文件的 Diff，比如 B 的变更。

git log -p --full-diff -- git log -p -- src/components/cmdb/components/A.vue
