Windows: git commit -a sends wrong networked drive path to editor

Question

With the repo on Windows networked drive, "git commit -a" sends the wrong path to the text editor.

When the repo is on an internal drive, "git commit -a" works as expected, the text editor is opened with Repo\.git\COMMIT_EDITMSG, and git waits until the file is edited, saved and the editor is closed.

But for a repo on a networked drive, git sends to the editor the path

\\readyshare\USB_Storage\Repo\readyshare\USB_Storage\Repo\.git\COMMIT_EDITMSG

which is wrong. This should have been

\\readyshare\USB_Storage\Repo\.git\COMMIT_EDITMSG

Or equivalently git using the windows path

Z:\Repo\.git\COMMIT_EDITMSG

This happens both on W7 and W10, git version 2.39.0.windows.2 (and earlier).

Does anyone know how to fix this?

Answer 1

After some interaction on github (https://github.com/git-for-windows/git/issues/4207) it turned out that the issue was not with git, but with the editor I set as core.editor, TextPad 6.
