On windows whole files cannot be added as context

On windows whole files cannot be added as context because llm interprets the drive part of the path as a fragment loader.

❯ D:\temp\runvenv-llm.bat --td -u -f "C:\Users\mraveloarinjaka\projects\MyConfig\init_shortcuts.sh" "explain that code" Error: Unknown fragment prefix: C

This seems expected given the code at https://github.com/simonw/llm/blob/921fae9a0ad3d664a872e35e4639b16089b61c1d/llm/cli.py#L134

I am not sure whether this should be solved in sllm or if we can add a specific path fragment loader in llm to be explicit
