Suport paths in lex_bareword

[doriath]

It is allowed to pass a path as bareword in nu, e.g. in ls or use commands.

The new lexer will replace this code, so let's not land it. I'll keep it open, though, as a reminder to make sure paths work with the new lexer.

The new lexer will significantly change / replace both the lexing and some of the parsing parts, so if you're looking for contributions, it's best to stick with the Resolver / Typechecker for now.

I wanted to look into modules and overlays, and the first thing I realized is that I can't do use foo.nu * because foo.nu does not parse correct.

• If the main concern is that this completely goes away with new parser, I would still just merge it
• if this will cause issues for you with merging the new parser/lexer, then indeed let's not merge (and I will continue iterating on modules / overlays on top of it, without submitting it to main branch)
