描述

Right now the log starts from HEAD - no matter if that's a tip of a branch or not.

For #81 we need to do the revwalk from every tip and come up with a smart data structure that allows us to draw the correct graph without storing the whole graph in memory.

Before tackling #81 we can at least determine if we are on a detached head and then iterate the branches whether one is a descendent of our current HEAD and then start from the branch tip and visualize where HEAD is in the log.

研究方向
The issue requires modifying the log display to start from the branch tip when HEAD is detached. First, examine the current log implementation in the repository, likely in the 'log' or 'graph' module. Use the libgit2 function `git graph descendant of` to check if any branch tip is a descendant of the current HEAD (detached). Then adjust the revision walk to start from that branch tip and show where HEAD is in the log. Refer to issue #81 for context on the desired data structure for graph drawing. The implementation should not store the full graph in memory but use a smart approach. There are no linked PRs or comments, so this is open for contribution.
