Subject: [ruby-core:96782] [Ruby master Feature#8709] Dir.glob should return	sorted file list

Issue #8709 has been updated by Eregon (Benoit Daloze).


Here are some benchmark results in the ruby repository:
```
$ ruby -e 'p Dir["**/*"].size'
12171

$ ruby -rbenchmark -e '10.times { p Benchmark.realtime { Dir["**/*"] } }'     
0.017877419999422273
0.015390422999189468
0.015255956001055893
0.015021605999208987

0.015358253996964777
0.014319942998554325

$ ruby -rbenchmark -e '10.times { p Benchmark.realtime { Dir["**/*"].sort } }'
0.017600111998035572
0.017109740001615137
0.017832364999776473
0.01726310600133729

0.017515739000373287
0.01770434499849216
```

So a bit slower but we can likely optimize further if desired.

Feature #8709: Dir.glob should return sorted file list

----------------------------------------
On OS X, Dir.glob and Dir[] return an ordered list of files.

On Ubuntu Linux, they do not and one must manually sort them.

Returning a list of files that isn't in order fails the Principle of Least Astonishment.

I attach a unit test to demonstrate ideal behaviour.
