Fish shell annoyances

[gabebw]

I'm listing them here as they come up just in case I want to switch back. Or perhaps these are already fixed, and I just don't know Fish well enough yet.

1. Globs are not case-insensitive (e.g. ls a* finds only files starting with a, not A)
2. There's no "range" globbing, like ls [A-Z]* a. https://github.com/fish-shell/fish-shell/issues/1187
3. There is no globbing even without a range, like ls [ABC]*

The only globbing that works is with curly braces: foo{1,2,3}.
