`grep` tool failing on Windows directory paths

[jamwil]

Issue

I'm a bit baffled by this one. On Windows, when I ask aider-ce to demonstrate use of the grep tool, I get a response like below:

⚙️ Executing rg: 'C:\Users\username\AppData\Local\Microsoft\WinGet\Packages\BurntSushi.ripgrep.MSVC_Microsoft.Winget.Source_8wekyb3d8bbwe\ripgrep-14.1.1-x86_64-pc-windows-msvc\rg.EXE' -n
-B 1 -A 1 -F -g '*.py' show_status 'C:\Users\username\projects\codebase\src'
The filename, directory name, or volume label syntax is incorrect.

What is odd is that I can take the exact command and run it directly and it works just fine. There's nothing wrong with the path at all. This I think may have something to do with the way the search directory path is serialized using str and passed to the command runner. If you pass a pathlib.WindowsPath through str, it escapes the backslashes, and I tried manually passing double-backslashes into the ripgrep and it handled it just fine.

Merged into the coroutine-experiment branch which I will merge into main later today. Thanks!
