Missing prompt autocomplete options on case-sensitive filesystems

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

Type out a directory containing files with the same name but differing case, hit tab to get suggestions

Expected behavior

Shows the available files

Actual behavior

Only shows one of them, furthermore it appears to be random which one it chooses

Error details

If you type a non-displayed option manually, then hit tab, pwsh "corrects" you to the wrong file..

Hm, 2.3.1-beta1 does solve this immediate issue, but it has strange behaviour (for a linux user) where it still thinks distinct filename stems are the same (but at least displays them now). I actually like this, but touch a1 Ax; ./a[tab] shows both a1 and Ax as options; a & A are distinct glyphs and only a1 was expected as a valid autocomplete.

Now if this is intended then that’s great! Pulling away from bash-esque constraints of needing to be so specific will make CLI much easier, and is definitely a strength of pwsh. But I would probably submit that files beginning with á et cetera should also match, which otherwise are much more annoying to type than mere case sensitivity, this would make pwsh absolutely amazing.

If it’s not intended though and is a side-effect of just fixing this immediate issue there might be side-effects to look into… so just checking.
