tests: fix another multi-statement hook for Windows

The double quotes are necessary, otherwise it tries to pipe into a program named
'short'.  An '&' could serve as a command separator on Windows instead of ';',
but I don't see any obvious way to swap these depending on the platform.  In
this case though, there really wasn't a need for multiple statements.
