[BUG] `%s` arguments are concatenated

[midrare]

Description
If you use %s with more than one argument, the first two args get concatenated. For example, demo.exe 1 2 3 results in ["12", "3"] being sent to the exe.

win-shim version: 1.1.2
Windows 11 Pro 22H2

Reproducible demo

C:\bin>shmake -i "cmd.exe" -o demo.exe -a "/c echo %s"

virtualizing 'cmd.exe'
       input: C:\Windows\SYSTEM32\cmd.exe

        args: /c echo %s

extracting terminal shim... ok.
mirroring properties... ver... icon... ok.
configuring startup sequence... ok.
