[Feature Request] Autocomplete brace expansion

[jyn514]

Current behavior:

$ ls examples
jit.rs  kaleidoscope
$ ls examples{j<tab>  # tab has no effect

Requested behavior:

$ ls examples{j<tab>  # tab autocompletes `examples/{jit.rs}`

FWIW bash doesn't do this.

On second thought, that should probably complete to examples/{jit.rs so that it only completes unambiguously.

One issue is that when you have something like examples/{j, there could also be a file called {jit.rs in addition to jit.rs.

The { is ambiguous without the closing }, which hasn't been typed yet.

Not saying we shouldn't do this, but it's something to consider. I haven't thought about how hard this is either -- it may be hard.

Possible a more common issue is #227, single quoted paths.
