/undo will do a git checkout which modify ALL files mtime

[jasonwch]

Description

This is a serious bug (found out from log), when I use /undo command, it will perform the following action:

git --git-dir= --work-tree=/myworkingfolderwithgit -- .

This make ALL tracked files inside "/myworkingfolderwithgit" update its modified time. Now I cannot restore the original file modified timestamp. I can only do git restore-mtime to restore to initial commit timestamp.

Please fix this seriously

That issue was filed specifically about /redo but covers the same underlying snapshot restore mechanism.
