CoPilot CLI unusable in Git VFS repositories

[mziller]

Describe the bug

CoPilot CLI 1.0.11 spawns several dozen "git.exe merge-base HEAD origin/HEAD" processes consuming all of memory. It does this for every single git.exe operation performed. That may be OK for some repos, but it is not a cheap operation for large VFS enabled repos, making GitHub CoPilot CLI unusable here.
