----------------------------------------
if ENV['PATH'] include double quotes, Kernel.system cann't find it.

windows OS, open a cmd window

```
set PATH="C:\Program Files\7-Zip";%PATH%
7z -h  # can run it

pry
system '7z -h'   # can't find 
```

and, if command include double quotes, system can't find too.

```
system '"C:\Program Files\7-Zip\7z" -h'  # ok
system '"C:\Program Files\7-Zip"\7z -h'  # can't find
system '"C:\Program Files\7-Zip\"7z -h'  # can't find
```
