start-process has weird parsing rules and buggy behavior. we've already had to work around them several times, and the workarounds were not complete.
i wonder who could have added it HMMMMMM
```
PS C:\Users\jyn\src\rust> git log --reverse -S Start-Process x.ps1
commit 775c3c0493
Author: Jynn Nelson <github@jyn.dev>
Date: Sun Jul 31 14:02:31 2022 -0500
Add `x.sh` and `x.ps1` shell scripts
```
the latest broken thing is trailing backslashes:
```
$ x.ps1 t .\tests\ui\error-emitter\
```
would be transformed into
```
['t', '.\\tests\\ui\\error-emitter"']
```
rather than trying to hack around that too, abandon start-process altogether and just use `&`.
