[Tinycc-devel] Help: How to delete my commit completely by git?

[lifenjoiner]

Hi everyone,

I am not going to join in breaking the code. I have only 2 commits for a long 
time. The recent one has poor thinking. I am going to delete it completely in 
case of anyone be suspicious.

Can somebody give me some advice to do it? I am not familiar with git. Ensure I 
won't do it wrong. Practical commands are the best.

Best wishes,
YX Hao
