Deadgrep lacks multi-directory support available through rg about deadgrep HOT 2 OPEN

To clarify, I'm interested in supporting '("/path/to/src" "/cache/path/to/lib1/src" "/cache/path/to/lib2/src") as the general case, with "/path/to/src" converted to '("/path/to/src") for backwards compatibility. Sometimes its useful to search across all of my library sources; sometimes it isn't.

I think the reference to overriding glob and ignore rules just means "if you ask for any specific path on the command line, we trust that you really want it and we won't try to hide it from you".

Interesting, I didn't know this was possible with rg. Looking at the docs:

    <PATH>...    
            A file or directory to search. Directories are searched recursively. Paths specified on
            the command line override glob and ignore rules.  

I think the best option here is to allow deadgrep-project-root-function to return a list, as you say. However, I don't think returning "/foo" will be the same as returning '("foo"), because passing a list of paths doesn't have the globbing or gitignore features.
